SET MOVE SEQUENCE - Move a sequence from one Slony-I replication set to another
SET MOVE SEQUENCE (options);
Change the set a sequence belongs to. The current set and the new set must originate on
the same node and subscribed by the same nodes.
Due to the way subscribing to new sets works make absolutely sure that the sub‐
scription of all nodes to the sets is completely processed before moving sequences.
Moving a sequence too early to a new set causes the subscriber to try and add the
sequence already during the subscription process, which fails with a duplicate key
error and breaks replication.
ORIGIN = ival
Origin node for the set. A future version of slonik might figure out this informa‐
tion by itself.
ID = ival
Unique ID of the sequence.
NEW SET = ival
Unique ID of the set to which the sequence should be moved.
This uses “schemadocsetmovesequence(p_new_set_id integer, p_seq_id integer)” [not avail‐
able as a man page].

ORIGIN = 1,
ID = 20,
NEW SET = 3
No application-visible locking should take place.
SLONIK EVENT CONFIRMATION BEHAVIOUR
Slonik waits for the command submitted to the previous event node to be confirmed on the
specified event node before submitting this command.
