Drop a node. This command removes the specified node entirely from the replication systems configuration. If the replication daemon is still running on that node (and processing events), it will attempt to uninstall the replication system and terminate itself.
Node ID of the node to remove.
Node ID of the node to generate the event; default is 1.
This uses schemadocdropnode( integer ).
When you invoke DROP NODE, one of the steps is to run UNINSTALL NODE.
When dropping triggers off of application tables, this will require exclusive access to each replicated table on the node being discarded.
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-DROP NODE state of things, and you will get error messages indicating missing OIDs.
After dropping a node, you may also need to recycle connections in your application.
You cannot submit this to an EVENT NODE that is the number of the node being dropped; the request must go to some node that will remain in the cluster.
