drop_trigger(5)

NAME

       DROP TRIGGER - remove a trigger

SYNOPSIS

       DROP TRIGGER [ IF EXISTS ] name ON table [ CASCADE | RESTRICT ]

DESCRIPTION

       DROP  TRIGGER  will  remove  an existing trigger definition. To execute
       this command, the current user must be the owner of the table for which
       the trigger is defined.

PARAMETERS

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

       name   The name of the trigger to remove.

       table  The name (optionally schema-qualified) of the  table  for  which
              the trigger is defined.

       CASCADE
              Automatically drop objects that depend on the trigger.

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

EXAMPLES

       Destroy the trigger if_dist_exists on the table films:

       DROP TRIGGER if_dist_exists ON films;

COMPATIBILITY

       The DROP TRIGGER statement in PostgreSQL is incompatible with  the  SQL
       standard.  In  the SQL standard, trigger names are not local to tables,
       so the command is simply DROP TRIGGER name.
