# 8.98. setaddsequence(p_seq_comment integer, p_fqname integer, p_seq_id text, p_set_id text)

Function Properties

Language: PLPGSQL

Return Type: bigint

setAddSequence (set_id, seq_id, seq_fqname, seq_comment) On the origin node for set set_id, add sequence seq_fqname to the replication set, and raise SET_ADD_SEQUENCE to cause this to replicate to subscriber nodes.
