NAME
SET MOVE SEQUENCE - Move a sequence from one Slony-I replication set to another
SYNOPSIS
SET MOVE SEQUENCE (options);
DESCRIPTION
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. Caution Due to the way subscribing to new sets works make absolutely sure that the subscription 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 information 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 available as a man page].
EXAMPLE
SET MOVE SEQUENCE ( ORIGIN = 1, ID = 20, NEW SET = 3 );
LOCKING BEHAVIOUR
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.
VERSION INFORMATION
This command was introduced in Slony-I 1.0.5 22 September 2023 SLONIK SET MOVE SEQUENCE(7)
