SET MOVE SEQUENCE

## 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( integer, integer ).

## Example

    SET MOVE SEQUENCE (
        ORIGIN = 1,
        ID = 20,
        NEW SET = 3
    );

## Locking Behaviour

No application-visible locking should take place.

## Version Information

This command was introduced in Slony-I 1.0.5
