Congratulations and thanks to all involved! Do I understand correctly that, at this time, while PG has data sharding and partitioning capabilities, it does not offer some related features found in Citus Open Source (shard rebalancer, distributed SQL engine and transactions) and in Citus on Azure aka Hyperscale (HA and streaming replication, tenant isolation - I'm especially interested in the latter one)? Are there any plans for PG to move toward this direction?
Streaming replication is supported as per https://www.postgresql.org/docs/current/warm-standby.html#ST... . You can likely build shard rebalancing and tenant isolation on top of the existing logical replication featureset. There are some groundwork features for distributed transactions (PREPARE TRANSACTION, COMMIT PREPARED, ROLLBACK PREPARED), but they're not supported as such.
