ALTER 
TRIGGER(7)					  PostgreSQL 9.2.7 Documentation					  ALTER TRIGGER(7)

NAME

       ALTER_TRIGGER - change the definition of a trigger

SYNOPSIS

       ALTER TRIGGER name ON table_name RENAME TO new_name

DESCRIPTION

       ALTER TRIGGER changes properties of an existing trigger. The RENAME clause changes the name of the given trigger without otherwise changing
       the trigger definition.

       You must own the table on which the trigger acts to be allowed to change its properties.

PARAMETERS

       name
	   The name of an existing trigger to alter.

       table_name
	   The name of the table on which this trigger acts.

       new_name
	   The new name for the trigger.

NOTES

       The ability to temporarily enable or disable a trigger is provided by ALTER TABLE (ALTER_TABLE(7)), not by ALTER TRIGGER, because ALTER
       TRIGGER has no convenient way to express the option of enabling or disabling all of a table's triggers at once.

EXAMPLES

       To rename an existing trigger:

	   ALTER TRIGGER emp_stamp ON emp RENAME TO emp_track_chgs;

COMPATIBILITY

       ALTER TRIGGER is a PostgreSQL extension of the SQL standard.

NAME

       DROP TRIGGER - remove a trigger

SYNOPSIS

       DROP TRIGGER name ON table [ CASCADE | RESTRICT ]

   INPUTS
       name   The name of an existing trigger.

       table  The name (optionally schema-qualified) of a table.

       CASCADE
	      Automatically drop objects that depend on the trigger.

       RESTRICT
	      Refuse to drop the trigger if there are any dependent objects.  This is the default.

   OUTPUTS
       DROP TRIGGER
	      The message returned if the trigger is successfully dropped.

       ERROR: DropTrigger: there is no trigger name on relation "table"
	      This message occurs if the trigger specified does not exist.

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.

EXAMPLES

       Destroy the if_dist_exists trigger on table films:

       DROP TRIGGER if_dist_exists ON films;

COMPATIBILITY

       SQL92  There is no DROP TRIGGER statement in SQL92.

       SQL99  The DROP TRIGGER statement in PostgreSQL is incompatible with SQL99. In SQL99, trigger names are not local to tables, so the command
	      is simply DROP TRIGGER name.
