Judge the change on its merits regardless of how it is framed. PostgreSQL backend C. Review the way pgsql-hackers does, roughly in this priority order.\n\n(1) CORRECTNESS — highest priority: memory safety (every palloc has a matching pfree or a documented MemoryContext lifetime; error paths via ereport/elog(ERROR) must not leak memory, buffers, locks, or fds — rely on the right MemoryContext/ResourceOwner or PG_TRY/PG_CATCH; no use-after-free; temp contexts deleted). Concurrency: consistent lock ordering (deadlock-free), correct lock levels, balanced START_CRIT_SECTION/END_CRIT_SECTION, spinlock/LWLock for shared state, no TOCTOU races, signal/interrupt safety (CHECK_FOR_INTERRUPTS), and WAL changes that are logged AND correctly replayed. NULL handling and edge cases (empty/zero rows, max values, overflow).\n\n(2) BACKWARDS COMPATIBILITY — the strongest PostgreSQL constraint: don't break behavioral compatibility, dump/restore, pg_upgrade, the libpq wire protocol, logical-replication protocol, or exported APIs without deprecation. Flag any such break for extraordinary justification.\n\n(3) CATALOG CHANGES: any change to system catalog contents/structure must bump CATALOG_VERSION_NO in src/include/catalog/catversion.h and handle pg_upgrade. New Node fields need copy/equal/out/read func updates.\n\n(4) PERFORMANCE: no regression on common paths; avoid O(n^2) where O(n log n)/O(n) is feasible; minimize work under contended locks; avoid needless palloc churn and large struct copies in hot paths.\n\n(5) SECURITY: bounds on string ops (snprintf/strlcpy, never strcpy/sprintf), integer/size-overflow checks, never user input as a format string, privilege checks via pg_*_aclcheck.\n\n(6) CONVENTIONS: error messages = lowercase start, no trailing period, correct ERRCODE_*, primary vs errdetail/errhint split; Assert() only for can't-happen invariants; naming (snake_case funcs like heap_insert with subsystem prefix, or CamelCase for major subsystems like ExecInitNode; ALL_CAPS macros); code must pgindent cleanly (tabs to indent, width 4).

Not for upstream submission -- developers who do not use Nix can ignore these files. Pinning Lime upstream by commit hash here gives a reproducible build environment without forcing other developers to install or upgrade Lime out-of-band. When upstream Lime cuts a new release the maintainer bumps flake.lock alongside the meson.build version floor. The full bison-to-Lime migration series is independent of these files; non-Nix contributors who install Lime via their package manager (or build it from source per installation.sgml) get the same end result. --- flake.lock | 243 +++++++++++++++++ flake.nix | 76 ++++++ pg-aliases.sh | 658 ++++++++++++++++++++++++++++++++++++++++++++ shell.nix | 733 ++++++++++++++++++++++++++++++++++++++++++++++++++

Subsequent commits port flex+bison grammars to Lime one component at a time; each is independently bisectable, so this commit on its own is a no-op for the runtime. What's added: * src/tools/pglime -- Python wrapper that invokes `lime` for custom_target() rules in component meson.build files. Handles --output-dir, --aot, --jit-compatible flags. * src/tools/lime_lint, lime_format, lime_format_check -- user-facing helper scripts driving `lime -L` (lint) and `lime -F` (format) over .lime files. * meson.build: - dependency('lime', required: false, version: '>=1.3.1') plus dependency('lime-compiler') for the in-process snapshot-build library shipped from v0.9.4 onwards (LTS line through v1.3.1). - find_program('lime', native: true) for the code-generation path. - lime_cmd kwargs dict consumed by per-component custom_target rules in subsequent commits. * meson_options.txt: - LIME option for explicit lime-binary path. - lime_aot feature (default 'auto') gating Lime's AOT-compiled action-table code path. * src/makefiles/meson.build -- pgxs export so out-of-tree contrib modules can find the Lime tooling. * src/tools/pgindent/pgindent -- recognise Lime's static_library helpers as proper C functions (cosmetic).

Each component gets its own per-grammar yytype.h header (repl_gram_yytype.h, syncrep_parse.h) declaring the YYSTYPE union shared between the parser action bodies and the scanner. The scanner driver code (syncrep_scanner.c, repl_scanner.c) is hand-rolled C; it sits between the Lime-emitted lex DFA and the Lime-emitted parser table-driven dispatch, translating internal sentinel codes into parser tokens with appropriate yylval shaping. Both grammars are small (syncrep: ~120 lines; repl: ~450 lines) and the SQL surface they parse is unchanged. All recovery and replication-protocol regression tests pass byte-identically with the new Lime backends. Per-component meson.build wraps the Lime-generated .c files in a static_library with c_args ['-Wno-missing-prototypes', '-Wno-unused-variable'] -- the Lime template emits both classes of warning by design. The relax stays local to the generated .c; the hand-rolled drivers compile under PG's standard -Wall flags. --- src/backend/replication/.gitignore | 3 +- src/backend/replication/Makefile | 28 +- src/backend/replication/meson.build | 49 +- src/backend/replication/repl_gram.lime | 468 ++++++++++++++++++++ src/backend/replication/repl_gram.y | 448 ------------------- src/backend/replication/repl_gram_yytype.h | 61 +++ src/backend/replication/repl_scanner.c | 408 +++++++++++++++++ src/backend/replication/repl_scanner.l | 350 --------------- src/backend/replication/repl_scanner.lex | 186 ++++++++ src/backend/replication/syncrep_gram.lime | 151 +++++++ src/backend/replication/syncrep_gram.y | 119 ----- src/backend/replication/syncrep_parse.h | 91 ++++ src/backend/replication/syncrep_scanner.c | 214 +++++++++ src/backend/replication/syncrep_scanner.l | 220 --------- src/backend/replication/syncrep_scanner.lex | 154 +++++++ src/include/replication/walsender_private.h | 4 +- 16 files changed, 1778 insertions(+), 1176 deletions(-) create mode 100644 src/backend/replication/repl_gram.lime delete mode 100644 src/backend/replication/repl_gram.y create mode 100644 src/backend/replication/repl_gram_yytype.h create mode 100644 src/backend/replication/repl_scanner.c delete mode 100644 src/backend/replication/repl_scanner.l create mode 100644 src/backend/replication/repl_scanner.lex create mode 100644 src/backend/replication/syncrep_gram.lime delete mode 100644 src/backend/replication/syncrep_gram.y create mode 100644 src/backend/replication/syncrep_parse.h create mode 100644 src/backend/replication/syncrep_scanner.c delete mode 100644 src/backend/replication/syncrep_scanner.l create mode 100644 src/backend/replication/syncrep_scanner.lex diff --git a/src/backend/replication/.gitignore b/src/backend/replication/.gitignore index 77d5a51068dff..921c33ca8e177 100644 --- a/src/backend/replication/.gitignore +++ b/src/backend/replication/.gitignore @@ -1,6 +1,5 @@ /repl_gram.h /repl_gram.c -/repl_scanner.c /syncrep_gram.h /syncrep_gram.c -/syncrep_scanner.c +/syncrep_gram.out diff --git a/src/backend/replication/Makefile b/src/backend/replication/Makefile index 7f867ee91dda8..31b413577a9ef 100644 --- a/src/backend/replication/Makefile +++ b/src/backend/replication/Makefile @@ -30,28 +30,26 @@ SUBDIRS = logical include $(top_srcdir)/src/backend/common.mk -# See notes in src/backend/parser/Makefile about the following two rules -repl_gram.h: repl_gram.c - touch $@ +# repl_gram and syncrep_gram are now generated by Lime (see +# src/tools/pglime).

It's a small grammar (~200 productions) and parses a fixed file generated at build time, so the test surface is initdb itself. The hand-rolled bootscanner.c is a thin driver shim around the Lime-emitted lex DFA. Keyword recognition still uses ScanKeywordLookup against bootkw.h (unchanged). initdb runs end-to-end against the new parser/scanner pair with byte-identical catalog output. --- src/backend/bootstrap/.gitignore | 1 - src/backend/bootstrap/Makefile | 14 +- src/backend/bootstrap/boot_gram_yytype.h | 60 +++ src/backend/bootstrap/bootparse.lime | 514 +++++++++++++++++++++++ src/backend/bootstrap/bootparse.y | 499 ---------------------- src/backend/bootstrap/bootscanner.c | 299 +++++++++++++ src/backend/bootstrap/bootscanner.l | 165 -------- src/backend/bootstrap/bootscanner.lex | 122 ++++++ src/backend/bootstrap/meson.build | 29 +- 9 files changed, 1022 insertions(+), 681 deletions(-) create mode 100644 src/backend/bootstrap/boot_gram_yytype.h create mode 100644 src/backend/bootstrap/bootparse.lime delete mode 100644 src/backend/bootstrap/bootparse.y create mode 100644 src/backend/bootstrap/bootscanner.c delete mode 100644 src/backend/bootstrap/bootscanner.l create mode 100644 src/backend/bootstrap/bootscanner.lex diff --git a/src/backend/bootstrap/.gitignore b/src/backend/bootstrap/.gitignore index 6351b920fd6b7..16e71d1a74913 100644 --- a/src/backend/bootstrap/.gitignore +++ b/src/backend/bootstrap/.gitignore @@ -1,3 +1,2 @@ /bootparse.h /bootparse.c -/bootscanner.c diff --git a/src/backend/bootstrap/Makefile b/src/backend/bootstrap/Makefile index 509b51e648311..adac4a4a06ac5 100644 --- a/src/backend/bootstrap/Makefile +++ b/src/backend/bootstrap/Makefile @@ -19,16 +19,18 @@ OBJS = \ include $(top_srcdir)/src/backend/common.mk -# See notes in src/backend/parser/Makefile about the following two rules -bootparse.h: bootparse.c - touch $@ +# bootparse is now generated by Lime (see src/tools/pglime).

This is one of the larger ports in the migration: jsonpath_scan.lex carries four exclusive states (XQ for double-quoted strings, XNQ for unquoted identifiers, XVQ for $variable references, XC for comments) and combined rules sharing escape- sequence handling. The driver (jsonpath_scan.c) post-processes the lexer's emitted tokens via a small set of internal sentinel codes (JP_TOK_STRING_TAKE / VARIABLE_TAKE / NUMERIC_TEXT / INT_TEXT / RAW_CHAR / VARIABLE_BARE) before handing them to the Lime parser. A small expected-output update lands for jsonpath.out and sqljson_queryfuncs.out: Lime's syntax-error messages on a few already-failing inputs differ from Bison's at the exact column, which the test cases assert. The changes are cosmetic; the actual error condition (and SQL-visible behaviour) is byte- identical to the bison parser. --- src/backend/utils/adt/.gitignore | 1 - src/backend/utils/adt/Makefile | 15 +- src/backend/utils/adt/jsonpath_gram.lime | 692 +++++++++++ src/backend/utils/adt/jsonpath_gram.y | 717 ----------- src/backend/utils/adt/jsonpath_internal.h | 92 +- src/backend/utils/adt/jsonpath_scan.c | 1088 +++++++++++++++++ src/backend/utils/adt/jsonpath_scan.l | 749 ------------ src/backend/utils/adt/jsonpath_scan.lex | 389 ++++++ .../utils/adt/jsonpath_scan_lex_internal.h | 98 ++ src/backend/utils/adt/meson.build | 27 +- 10 files changed, 2377 insertions(+), 1491 deletions(-) create mode 100644 src/backend/utils/adt/jsonpath_gram.lime delete mode 100644 src/backend/utils/adt/jsonpath_gram.y create mode 100644 src/backend/utils/adt/jsonpath_scan.c delete mode 100644 src/backend/utils/adt/jsonpath_scan.l create mode 100644 src/backend/utils/adt/jsonpath_scan.lex create mode 100644 src/backend/utils/adt/jsonpath_scan_lex_internal.h diff --git a/src/backend/utils/adt/.gitignore b/src/backend/utils/adt/.gitignore index 7fab054407eca..42d6d7b6533dc 100644 --- a/src/backend/utils/adt/.gitignore +++ b/src/backend/utils/adt/.gitignore @@ -1,3 +1,2 @@ /jsonpath_gram.h /jsonpath_gram.c -/jsonpath_scan.c diff --git a/src/backend/utils/adt/Makefile b/src/backend/utils/adt/Makefile index 0c7621957c183..a219c06d018c8 100644 --- a/src/backend/utils/adt/Makefile +++ b/src/backend/utils/adt/Makefile @@ -132,21 +132,18 @@ OBJS = \ xid8funcs.o \ xml.o -# See notes in src/backend/parser/Makefile about the following two rules -jsonpath_gram.h: jsonpath_gram.c - touch $@ +# jsonpath_gram is generated by Lime (see src/tools/pglime). +jsonpath_gram.h: jsonpath_gram.c ; -jsonpath_gram.c: BISONFLAGS += -d - -jsonpath_scan.c: FLEXFLAGS = -CF -p -p -jsonpath_scan.c: FLEX_NO_BACKUP=yes +jsonpath_gram.c: jsonpath_gram.lime + lime -d. $< # Force these dependencies to be known even without dependency info built: -jsonpath_gram.o jsonpath_scan.o: jsonpath_gram.h +jsonpath_gram.o jsonpath_scan.o: jsonpath_gram.h jsonpath_gram_yytype.h clean: rm -f lex.backup - rm -f jsonpath_gram.c jsonpath_gram.h jsonpath_scan.c + rm -f jsonpath_gram.c jsonpath_gram.h jsonpath_gram.out like.o: like.c like_match.c diff --git a/src/backend/utils/adt/jsonpath_gram.lime b/src/backend/utils/adt/jsonpath_gram.lime new file mode 100644 index 0000000000000..2d0ba96569a47 --- /dev/null +++ b/src/backend/utils/adt/jsonpath_gram.lime @@ -0,0 +1,692 @@ +/*------------------------------------------------------------------------- + * + * jsonpath_gram.lime + * Lime grammar for the jsonpath datatype. + * + * Ported byte-for-byte from the retired Bison grammar + * (src/backend/utils/adt/jsonpath_gram.y prior to Phase 2e). + * Every token and every production has a one-to-one counterpart in + * the original; every action builds the same JsonPathParseItem tree + * with the same field values. + * + * The hand-rolled scanner lives in jsonpath_scan.c.

This commit ports three coupled scanners and one parser: src/fe_utils/psqlscan.l -> psqlscan.lex (SQL lexer core, 11 states) src/bin/psql/psqlscanslash.l -> psqlscanslash.lex (slash-cmd parser, 8 states) src/bin/pgbench/exprparse.y -> exprparse.lime (pgbench expression parser) src/bin/pgbench/exprscan.l -> exprscan.lex (pgbench expression lexer) Strategy D (per-call lex): each psql_scan() call allocates a fresh Foo_Lexer over the remaining buffer slice, runs LexFeedBytes until the first stop point, frees. Cursor advance is tracked by the driver (StackElem.pos); variable-substitution ":varname" expansion uses the existing buffer_stack with recursive psql_scan into pushed StackElem. The pgbench expression lexer's INITIAL state (one-word-at-a-time expr_lex_one_word) stays hand-rolled -- it's too small to pay for porting and doesn't fit Lime's pre-scan-emit-callback shape. The EXPR state (the bulk of pgbench's expression syntax) is Lime-driven.

The original parser was scanner-only; no bison grammar. This commit ports the scanner to Lime's .lex format. The driver (guc-file.c) consumes a pre-scanned token FIFO; ConfigFileLineno is bumped on EOL token pop. Quoted-string values match a regex span and are post-processed via the existing DeescapeQuotedString -- the scanner doesn't need %literal_buffer here. Existing GUC config-file regression tests and SIGHUP-reload tests run unchanged after the port. --- src/backend/utils/misc/Makefile | 3 - .../utils/misc/{guc-file.l => guc-file.c} | 376 ++++++++++++------ src/backend/utils/misc/guc_file.lex | 128 ++++++ src/backend/utils/misc/guc_internal.h | 2 +- src/backend/utils/misc/meson.build | 24 +- 5 files changed, 396 insertions(+), 137 deletions(-) rename src/backend/utils/misc/{guc-file.l => guc-file.c} (67%) create mode 100644 src/backend/utils/misc/guc_file.lex diff --git a/src/backend/utils/misc/Makefile b/src/backend/utils/misc/Makefile index f142d17178bdd..1bb9d90f1ff91 100644 --- a/src/backend/utils/misc/Makefile +++ b/src/backend/utils/misc/Makefile @@ -44,6 +44,3 @@ endif guc_tables.o: guc_tables.c $(top_builddir)/src/backend/utils/guc_tables.inc.c include $(top_srcdir)/src/backend/common.mk - -clean: - rm -f guc-file.c diff --git a/src/backend/utils/misc/guc-file.l b/src/backend/utils/misc/guc-file.c similarity index 67% rename from src/backend/utils/misc/guc-file.l rename to src/backend/utils/misc/guc-file.c index 58669a67e050b..bee99370ed09b 100644 --- a/src/backend/utils/misc/guc-file.l +++ b/src/backend/utils/misc/guc-file.c @@ -1,12 +1,33 @@ -%top{ -/* - * Scanner for the configuration file +/*------------------------------------------------------------------------- + * + * guc-file.c + * Hand-rolled scanner for the PostgreSQL configuration-file grammar. + * + * Replaces the former guc-file.l (flex) without any grammar changes -- + * postgresql.conf (and every file that uses its "name = value" syntax) + * still accepts the same token stream, still builds the same + * ConfigVariable list, and still emits byte-identical error messages. + * + * The file is organized in two halves: + * + * 1.

Also retire ecpg's bison input (preproc.y) by feeding gram.lime through a reverse converter back to bison-shaped grammar text that ecpg's parse.pl reads. Backend SQL parser: src/backend/parser/gram.y -> gram.lime (~21k lines, mechanically translated) src/backend/parser/scan.l -> scan.lex (745 lines, 11 exclusive states) src/backend/parser/scan.c hand-rolled driver wrapping the Lime-emitted lex DFA in the public scanner.h API (core_yylex, scanner_init/finish, base_yylex's 2-token lookahead) The gram.lime file is mechanically derived from the previous gram.y by src/tools/lime_convert_gram.py: the converter rewrites %type / %union / mid-rule actions / @N location refs / inline char-literal terminals / %name-prefix etc. into Lime's idiom. Action bodies port verbatim modulo $$/$N rewriting. The converter is preserved in-tree so future gram.y-style edits can still be made (edit gram.y, run the converter, regenerate gram.lime), though for this commit gram.y itself is dropped. ecpg/preproc: src/interfaces/ecpg/preproc/pgc.l -> pgc.c (hand-rolled C) + pgc.lex (Lime .lex DFA; 21 exclusive states, ECPG-specific includes) src/interfaces/ecpg/preproc/parser.c bridge code ecpg historically generates its own preproc.y by running parse.pl over backend gram.y. parse.pl now reads gram.lime via src/tools/lime_to_bison_gram.py, a reverse converter that emits a bison-syntax skeleton. This keeps ecpg buildable without retargeting it to Lime in this commit (a future commit can do that independently). Public ABI of scanner.h preserved exactly: - core_yylex returns the same token codes as before - base_yylex's 2-token lookahead (NOT BETWEEN -> NOT_LA, etc.) runs unchanged - YYLLOC location offsets match bison's The conversion is byte-identical at the parse-tree level. Standard regress + ecpg suites pass. Three small expected- output adjustments land for graph_table.out, jsonpath.out, and sqljson_queryfuncs.out where Lime's syntax-error messages report the offending lookahead at a slightly different column than Bison's. These are cosmetic in user-visible behaviour; all SQL semantics unchanged. --- src/backend/Makefile | 11 +- src/backend/catalog/genbki.pl | 2 +- src/backend/jit/llvm/llvmjit.c | 24 +- src/backend/parser/.gitignore | 2 +- src/backend/parser/Makefile | 12 +- src/backend/parser/gram.lime | 21311 ++++++++++++++++ src/backend/parser/gram.y | 20941 --------------- src/backend/parser/gramparse.h | 72 + src/backend/parser/meson.build | 67 +- src/backend/parser/parser.c | 22 +- src/backend/parser/scan.c | 1194 + src/backend/parser/scan.l | 1430 -- src/backend/parser/scan.lex | 750 + src/backend/parser/scan_lex_internal.h | 202 + src/include/c.h | 14 +- src/interfaces/ecpg/preproc/.gitignore | 1 - src/interfaces/ecpg/preproc/Makefile | 9 +- src/interfaces/ecpg/preproc/ecpg.addons | 29 +- src/interfaces/ecpg/preproc/ecpg.header | 1 + src/interfaces/ecpg/preproc/meson.build | 82 +- src/interfaces/ecpg/preproc/parser.c | 136 +- src/interfaces/ecpg/preproc/pgc.c | 1506 ++ src/interfaces/ecpg/preproc/pgc.l | 1903 -- src/interfaces/ecpg/preproc/pgc.lex | 1483 ++ src/interfaces/ecpg/preproc/pgc_internal.h | 112 + src/interfaces/ecpg/preproc/preproc_extern.h | 1 + src/interfaces/ecpg/preproc/preproc_yytype.h | 49 + .../ecpg/test/expected/preproc-define.c | 10 +- src/test/regress/expected/graph_table.out | 4 +- src/test/regress/expected/jsonpath.out | 20 +- .../regress/expected/sqljson_queryfuncs.out | 2 +- src/test/regress/pg_regress.c | 2 +- src/tools/lime_convert_gram.py | 2524 ++ src/tools/lime_to_bison_gram.py | 475 + 34 files changed, 30020 insertions(+), 24383 deletions(-) create mode 100644 src/backend/parser/gram.lime delete mode 100644 src/backend/parser/gram.y create mode 100644 src/backend/parser/scan.c delete mode 100644 src/backend/parser/scan.l create mode 100644 src/backend/parser/scan.lex create mode 100644 src/backend/parser/scan_lex_internal.h create mode 100644 src/interfaces/ecpg/preproc/pgc.c delete mode 100644 src/interfaces/ecpg/preproc/pgc.l create mode 100644 src/interfaces/ecpg/preproc/pgc.lex create mode 100644 src/interfaces/ecpg/preproc/pgc_internal.h create mode 100644 src/interfaces/ecpg/preproc/preproc_yytype.h create mode 100755 src/tools/lime_convert_gram.py create mode 100755 src/tools/lime_to_bison_gram.py diff --git a/src/backend/Makefile b/src/backend/Makefile index 162d3f1f2a982..627a43aff166b 100644 --- a/src/backend/Makefile +++ b/src/backend/Makefile @@ -198,9 +198,8 @@ utils/probes.o: utils/probes.d $(SUBDIROBJS) generated-parser-sources: $(MAKE) -C parser gram.c gram.h scan.c $(MAKE) -C bootstrap bootparse.c bootparse.h bootscanner.c - $(MAKE) -C replication repl_gram.c repl_gram.h repl_scanner.c syncrep_gram.c syncrep_gram.h syncrep_scanner.c + $(MAKE) -C replication repl_gram.c repl_gram.h repl_scanner.c syncrep_gram.c syncrep_gram.h $(MAKE) -C utils/adt jsonpath_gram.c jsonpath_gram.h jsonpath_scan.c - $(MAKE) -C utils/misc guc-file.c ########################################################################## @@ -223,6 +222,10 @@ endif $(INSTALL_DATA) $(srcdir)/libpq/pg_ident.conf.sample '$(DESTDIR)$(datadir)/pg_ident.conf.sample' $(INSTALL_DATA) $(srcdir)/libpq/pg_hosts.conf.sample '$(DESTDIR)$(datadir)/pg_hosts.conf.sample' $(INSTALL_DATA) $(srcdir)/utils/misc/postgresql.conf.sample '$(DESTDIR)$(datadir)/postgresql.conf.sample' + $(MKDIR_P) '$(DESTDIR)$(datadir)/parser' + $(INSTALL_DATA) $(srcdir)/parser/gram.lime '$(DESTDIR)$(datadir)/parser/gram.lime' + $(MKDIR_P) '$(DESTDIR)$(includedir_server)/parser' + $(INSTALL_DATA) $(srcdir)/parser/gramparse.h '$(DESTDIR)$(includedir_server)/parser/gramparse.h' ifeq ($(with_llvm), yes) install-bin: install-postgres-bitcode @@ -282,7 +285,9 @@ endif rm -f '$(DESTDIR)$(datadir)/pg_hba.conf.sample' \ '$(DESTDIR)$(datadir)/pg_ident.conf.sample' \ '$(DESTDIR)$(datadir)/pg_hosts.conf.sample' \ - '$(DESTDIR)$(datadir)/postgresql.conf.sample' + '$(DESTDIR)$(datadir)/postgresql.conf.sample' \ + '$(DESTDIR)$(datadir)/parser/gram.lime' \ + '$(DESTDIR)$(includedir_server)/parser/gramparse.h' ifeq ($(with_llvm), yes) $(call uninstall_llvm_module,postgres) endif diff --git a/src/backend/catalog/genbki.pl b/src/backend/catalog/genbki.pl index 86f3135f9c79e..4b6022ee38885 100644 --- a/src/backend/catalog/genbki.pl +++ b/src/backend/catalog/genbki.pl @@ -1028,7 +1028,7 @@ sub print_bki_insert $bki_value =~ s/'/''/g; # Quote value if needed.
