Changes the definition of a trigger.
ALTER TRIGGER <name> ON <table> RENAME TO <newname>
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.
The ability to temporarily activate or deactivate a trigger is provided by ALTER TABLE, not by
ALTER TRIGGER, because
ALTER TRIGGER has no convenient way to express the option of activating or deactivating all of a table’s triggers at once.
Note that Greenplum Database has limited support of triggers in this release. See CREATE TRIGGER for more information.
To rename an existing trigger:
ALTER TRIGGER emp_stamp ON emp RENAME TO emp_track_chgs;
ALTER TRIGGER is a Greenplum Database extension of the SQL standard.
