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(l)], not by ALTER TRIGGER, because ALTER TRIG-
       GER has no convenient way to express the option  of  enabling  or  dis-
       abling 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.
