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.
To use ALTER RULE, you must own the table or view that the rule applies to.
name
The name of an existing rule to alter.
table_name
The name (optionally schema-qualified) of the table or view that the rule applies to.
new_name
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.
