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.
- IF EXISTS
Do not throw an error if the transform does not exist. A notice is issued in this case.
The name of the data type of the transform.
The name of the language of the transform.
Automatically drop objects that depend on the transform.
Refuse to drop the transform if any objects depend on it. This is the default.
To drop the transform for type hstore and language plpythonu:
DROP TRANSFORM FOR hstore LANGUAGE plpythonu;
This form of DROP TRANSFORM is a PostgreSQL extension. See CREATE TRANSFORM for details.
