ALTER RULE — change the definition of a rule
ALTER RULE name ON table_name RENAME TO new_name
ALTER RULE changes properties of an existing rule. Currently, the only available action is to change the rule's name.
ALTER RULE , you must own the table or view that the rule applies to.
- The name of an existing rule to alter.
- The name (optionally schema-qualified) of the table or view that the rule applies to.
- The new name for the rule.
To rename an existing rule:
ALTER RULE notify_all ON emp RENAME TO notify_me;
ALTER RULE is a PostgreSQL language extension, as is the entire query rewrite system.
