NAME
       DROP_RULE - remove a rewrite rule

SYNOPSIS
       DROP RULE [ IF EXISTS ] name ON table_name [ CASCADE | RESTRICT ]

DESCRIPTION
       DROP RULE drops a rewrite rule.

PARAMETERS
       IF EXISTS
           Do not throw an error if the rule does not exist. A notice is issued in this case.

       name
           The name of the rule to drop.

       table_name
           The name (optionally schema-qualified) of the table or view that the rule applies to.

       CASCADE
           Automatically drop objects that depend on the rule, and in turn all objects that
           depend on those objects (see Section 5.14).

       RESTRICT
           Refuse to drop the rule if any objects depend on it. This is the default.

EXAMPLES
       To drop the rewrite rule newrule:

           DROP RULE newrule ON mytable;

COMPATIBILITY
       DROP RULE is a PostgreSQL language extension, as is the entire query rewrite system.
