NAME

       DROP_TRANSFORM - remove a transform

SYNOPSIS

       DROP TRANSFORM [ IF EXISTS ] FOR type_name LANGUAGE lang_name

DESCRIPTION

       DROP TRANSFORM removes a previously defined transform.

       To be able to drop a transform, you must own the type and the language. These are the same
       privileges that are required to create a transform.

PARAMETERS

       IF EXISTS
           Do not throw an error if the transform does not exist. A notice is issued in this
           case.

       type_name
           The name of the data type of the transform.

       lang_name
           The name of the language of the transform.

       CASCADE
           Automatically drop objects that depend on the transform.

       RESTRICT
           Refuse to drop the transform if any objects depend on it. This is the default.

EXAMPLES

       To drop the transform for type hstore and language plpythonu:

           DROP TRANSFORM FOR hstore LANGUAGE plpythonu;

COMPATIBILITY
