pgsql: Add some additional tests for row filters in logical replication

Add some additional tests for row filters in logical replication.

Commit 52e4f0cd47 didn't add tests for pg_dump support, so add a few tests
for it. Additionally, verify that catalogs are updated after few
ALTER PUBLICATION commands that modify row filters by using \d.
