Can this please be merged? It's a blocking issue with Postgres 17. @kyleconroy |

There was a problem hiding this comment.
This seems a little aggressive to remove all lines that begin with \. The following is valid SQL, but would be broken by this fix
SELECT E'
\x61 b c
';
I don't think pg_dump would create such a statement but hand written SQL could.
I would suggest that the fix only exclude lines starting with \restrict and \unrestrict

This is kind of a lazy quick-and-dirty implementation that doesn't attempt to consolidate some duplicate line parsing that we do during migration removal and just sticks a func right in the package that handles file parsing for all engines, even though this line filter only applies to postgresql.
Happy to revise if there's a better place to put this.
