Issue with latest version of pglast

[grawlinson]

I was attempting to use the latest version of pglast with squabble, as the specified version of pglast was released back in 2019.

Keep getting these particular errors (see last line):

$ squabble --list-rules

Looks like there have been some pretty significant changes recently in pglast based on the ChangeLog, with several of them being backward incompatible. This project would need to be updated to reflect the new API to use it.

Which features of the new version of pglast are you interested in?
