Hi,

patch 0010 properly handles partitioned table creation on the apply
worker. Whether a replicated partitioned table should be added to
pg_subscription_rel catalog depends on the setting of
publish_via_partition_root of the publication. Thus we need to connect
to the source DB and check if the partitioned table is in
pg_catalog.pg_publication_tables after the apply worker creates the
partitioned table.

Thanks to Borui Yang for enabling and testing replication of DDL type
T_RenameStmt in patch 0009.

I've also rebased all the patches. Github branch of the same change
can be found here:
