DROP CAST

DROP CAST [ IF EXISTS ] (source_type AS target_type) [ CASCADE | RESTRICT ]

Description

DROP CAST removes a previously defined cast.

To be able to drop a cast, you must own the source or the target data type. These are the same privileges that are required to create a cast.

`IF EXISTS`: Do not throw an error if the cast does not exist. A notice is issued in this case.
*source_type*: The name of the source data type of the cast.
*target_type*: The name of the target data type of the cast.
`CASCADE`; `RESTRICT`: These key words do not have any effect, since there are no dependencies on casts.

To drop the cast from type text to type int:

DROP CAST (text AS int);

The DROP CAST command conforms to the SQL standard.
