Table of contents
Synopsis¶
DROP SERVER [ IF EXISTS ] name [, ...] [ CASCADE | RESTRICT ]
Description¶
DROP SERVER is a DDL statement that drops one or more foreign servers.
Dropping a server requires AL permission on cluster level.
Parameters¶
- name:
The name of the server to drop. Separate multiple names by comma to drop multiple servers at once.
Clauses¶
IF EXISTS¶
By default, DROP SERVER raises an error if the given servers don’t exist. If
the optional IF EXISTS clause is used, the statement won’t raise an error if
any servers listed don’t exist.
CASCADE | RESTRICT¶
RESTRICT causes DROP SERVER to raise an error if any foreign table or
user mappings for the given servers exist. This is the default.
CASCADE instead causes DROP SERVER to also delete all foreign tables and
mapped users using the given servers.
