ALTER TRIGGER — change the definition of a trigger
ALTER TRIGGERnameONtable_nameRENAME TOnew_nameALTER TRIGGERnameONtable_nameDEPENDS ON EXTENSIONextension_name
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.
nameThe name of an existing trigger to alter.
table_nameThe name of the table on which this trigger acts.
new_nameThe new name for the trigger.
extension_nameThe name of the extension that the trigger is to depend on.
The ability to temporarily enable or disable a trigger is
provided by ALTER TABLE,
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.
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;
ALTER TRIGGER is a PostgreSQL extension of the SQL standard.
