DROP RULE name [, ...]
The name of an existing rule to drop. You may drop multiple rules by specifying their names in a comma-delimited list.
Use the DROP RULE command to remove a rule from a PostgreSQL database. When a rule is dropped, the change is effective immediately. A rule becomes unavailable as soon as it is dropped, and its definition is completely removed from the database system.
The following example drops the sync_stock_with_editions rule:
booktown=# DROP RULE sync_stock_with_editions; DROP
