UNINSTALL NODE - Decommission Slony-I node

If you are using connections that cache query plans (this is particularly common for Java application frameworks with connection pools), the connections may cache query plans that include the pre-UNINSTALLNODE state of things, and you will get error messages indicating missing OIDs [“[MISSING TEXT]” [not available as a man page]]. After dropping a node, you may also need to recycle connections in your application.

Restores all tables to the unlocked state, with all original user triggers, constraints and rules, even‐ tually added Slony-I specific serial key columns dropped and the Slony-I schema dropped. The node becomes a standalone database. The data is left untouched. ID = ival Node ID of the node to uninstall. This uses “schemadocuninstallnode()” [not available as a man page]. The difference between UNINSTALLNODE and DROPNODE is that all UNINSTALLNODE does is to remove the Slony-I configuration; it doesn't drop the node's configuration from replication.

UNINSTALL NODE ( ID = 2 );

When dropping triggers off of application tables, this will require exclusive access to each replicated table on the node being discarded.
