TRIGGER(7)						   SQL Commands 						  ALTER TRIGGER(7)

NAME
       ALTER TRIGGER - change the definition of a trigger

SYNOPSIS
       ALTER TRIGGER name ON table RENAME TO newname

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  The name of the table on which this trigger acts.

       newname
	      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.
