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 trig-
              ger.

       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.
