ADMIN CONNINFO - preamble - identifying PostgreSQL database
NODE ival ADMIN CONNINFO = 'DSN';
] [ 'conninfo'
Describes how the slonik utility can reach a node's database in the cluster from
where it is run (likely the DBA's workstation). The conninfo string is the
string agrument given to the PQconnectdb()
The slonik utility will not try to connect to a given database unless some
subsequent command requires the connection.
As mentioned in the original documents, Slony-I is designed as an enterprise
replication system for data centers. It has been assumed throughout the entire
development that the database servers and administrative workstations involved
in replication and/or setup and configuration activities can use simple
authentication schemes like ‘trust’. Alternatively, libpq can
read passwords from .pgpass
If you need to change the DSN information for a node, as would happen if the IP
address for a host were to change, you must submit the new information using
the SLONIK STORE PATH
(7) command, and that configuration will be
propagated. Existing slon processes may need to be restarted in order to
become aware of the configuration change.
NODE 1 ADMIN CONNINFO = 'dbname=testdb host=server1 user=slony';
This command was introduced in Slony-I 1.0
