The latest release of all `pg_dump` major versions, going back to 13, started inserting `\restrict` `\unrestrict` keywords into dumps. This currently breaks sqlc in `gen/dump` and our check migration script. Full details of the postgres change are available here: https://git.postgresql.org/gitweb/?p=postgresql.git;a=commitdiff;h=575f54d4c To fix, we'll always use the `pg_dump` in our postgres 13.21 docker image for schema dumps, instead of what's on the runner/local machine. Coder doesn't restore from postgres dumps, so we're not vulnerable to attacks that would be patched by the latest postgres version. Regardless, we'll unpin ASAP. Once sqlc is updated to handle these keywords, we need to start stripping them when comparing the schema in the migration check script, and then we can unpin the pg_dump version. This is being tracked at coder/internal#965
