Thread: 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.

It uses -DRELCACHE_FORCE_RELEASE -DCATCACHE_FORCE_RELEASE, not sure if this could affect the result. cheers andrew -- Andrew Dunstan https://www.2ndQuadrant.com PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services
