Feature request: PSL support for Postgres scalar arrays (text[], uuid[])

[olgen]

Package and version

• prisma-next: 0.12.0
• @prisma-next/postgres: 0.12.0
• Node: v22.x
• Package manager: bun 1.3.x
• OS: macOS (darwin)

Desired behaviour

Postgres scalar array columns should infer to a first-class PSL type (or documented extension), not:

tags            Unsupported("text[]")
applicationIds  Unsupported("uuid[]") @map("application_ids")

Where the gap surfaces

Brownfield contract infer on Supabase / Postgres schemas with array columns. We hit this while inferring a production-adjacent schema (~30 tables).

Current workaround

Manually replace Unsupported("text[]") / Unsupported("uuid[]") with Json, which loses type precision at the contract and TypeScript layers.

Example from infer output

model UserTasks {
  tags Unsupported("text[]")
  // ...
}
