SLONIK CLUSTER NAME(7) Slonik Preamble Commands SLONIK CLUSTER NAME(7)NAME
CLUSTER NAME - preamble - identifying Slony-I cluster
SYNOPSIS
CLUSTER NAME = [ clustername; ]
DESCRIPTION
Must be the very first statement in every slonik script. It defines the
namespace in which all Slony-I specific functions, procedures, tables
and sequences are defined. The namespace name is built by prefixing the
given string literal with an underscore. This namespace will be identi‐
cal in all databases that participate in the same replication group.
No user objects are supposed to live in this namespace, and the names‐
pace is not allowed to exist prior to adding a database to the replica‐
tion system. Thus, if you add a new node using
pg_dump -s on a database that is already in the cluster of replicated
databases, you will need to drop the namespace via the SQL command
DROP SCHEMA _testcluster CASCADE; .
EXAMPLE
CLUSTER NAME = testcluster;
