pgsql: Fix error with CREATE PUBLICATION, wal_level=minimal, and new ta

Fix error with CREATE PUBLICATION, wal_level=minimal, and new tables.

CREATE PUBLICATION has failed spuriously when applied to a permanent
relation created or rewritten in the current transaction.  Make the same
change to another site having the same semantic intent; the second
instance has no user-visible consequences.  Back-patch to v13, where
commit c6b92041d38512a4176ed76ad06f713d2e6c01a8 broke this.
