DROP TRANSFORM

Removes a transform.

Synopsis​

DROP TRANSFORM [IF EXISTS] FOR <type_name> LANGUAGE <lang_name> [CASCADE | RESTRICT]

Description​

DROP TRANSFORM removes a previously defined transform.

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. Apache Cloudberry issues a notice 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.

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;

Compatibility​

This form of DROP TRANSFORM is a Apache Cloudberry extension. See CREATE TRANSFORM for details.
