6.93. replicate_partition(integer, text, text, text, text)

Function Properties

Language: PLPGSQL

Return Type: bigint

Add a partition table to replication. tab_idxname is optional - if NULL, then we use the primary key. This function looks up replication configuration via the parent table. Note that this function is to be run within an EXECUTE SCRIPT script, so it runs at the right place in the transaction stream on all nodes.
