ALTER TRIGGER(7)	 PostgreSQL 17.5 Documentation	      ALTER TRIGGER(7)

NAME
       ALTER_TRIGGER - change the definition of	a trigger

SYNOPSIS
       ALTER TRIGGER name ON table_name	RENAME TO new_name
       ALTER TRIGGER name ON table_name	[ NO ] DEPENDS ON EXTENSION extension_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. If the table that the
       trigger is on is	a partitioned table, then corresponding	clone triggers
       in the partitions are renamed too.

       The DEPENDS ON EXTENSION	clause marks the trigger as dependent on an
       extension, such that if the extension is	dropped, the trigger will
       automatically be	dropped	as well.

       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.

       extension_name
	   The name of the extension that the trigger is to depend on (or no
	   longer dependent on,	if NO is specified). A trigger that's marked
	   as dependent	on an extension	is automatically dropped when the
	   extension is	dropped.

NOTES
       The ability to temporarily enable or disable a trigger is provided by
       ALTER TABLE, 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;

       To mark a trigger as being dependent on an extension:

	   ALTER TRIGGER emp_stamp ON emp DEPENDS ON EXTENSION emplib;

COMPATIBILITY
       ALTER TRIGGER is	a PostgreSQL extension of the SQL standard.
