DROP TRANSFORM

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 5.13).
  • 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;
