ALTER TRIGGER(7)	PostgreSQL 9.6.19 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	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. 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.

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;

       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.
