This uses “schemadocdropnode( integer )” [not available as a man page].
When you invoke DROP NODE, one of the steps is to run UNINSTALL NODE.
DROP NODE ( ID = 2, EVENT NODE = 1 );
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 [“[MISSING TEXT]” [not available as a man page]].
After dropping a node, you may also need to recycle connections in your
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
This command was introduced in Slony-I 1.0
In version 2.0, the default value for EVENT NODE was removed, so a node
