Thread: [COMMITTERS] pgsql: Fix replication with replica identity full

Fix replication with replica identity full

The comparison with the target rows on the subscriber side was done with
datumIsEqual(), which can have false negatives.  For instance, it didn't
work reliably for text columns.  So use the equality operator provided
by the type cache instead.

Also add more user documentation about replica identity requirements.
