DROP TRANSFORM(7) PostgreSQL 16.9 Documentation DROP TRANSFORM(7)
NAME
DROP_TRANSFORM - remove a transform
SYNOPSIS
DROP TRANSFORM [ IF EXISTS ] FOR type_name LANGUAGE lang_name [ CASCADE | RESTRICT ]
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, and in
turn all objects that depend on those objects (see Section 5.14).
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 plpython3u:
DROP TRANSFORM FOR hstore LANGUAGE plpython3u;

TRANSFORM (CREATE_TRANSFORM(7)) for details.
