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.
