pgsql: Allow publishing partition changes via ancestors
Allow publishing partition changes via ancestors
To control whether partition changes are replicated using their own
identity and schema or an ancestor's, add a new parameter that can be
set per publication named 'publish_via_partition_root'.
This allows replicating a partitioned table into a different partition
structure on the subscriber.

prion seems to be persistently unhappy with this. It uses
-DRELCACHE_FORCE_RELEASE -DCATCACHE_FORCE_RELEASE, not sure if this
could affect the result.
