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.
