pgsql: Support adding partitioned tables to publication

Support adding partitioned tables to publication

When a partitioned table is added to a publication, changes of all of
its partitions (current or future) are published via that publication.

This change only affects which tables a publication considers as its
members.  The receiving side still sees the data coming from the
individual leaf partitions.  So existing restrictions that partition
hierarchies can only be replicated one-to-one are not changed by this.
