DESCRIPTION

14       DROP CAST removes a previously defined cast.
15
16       To  be  able to drop a cast, you must own the source or the target data
17       type. These are the same privileges that are required to create a cast.

PARAMETERS

20       IF EXISTS
21              Do not throw an error if the cast does not exist.  A  notice  is
22              issued in this case.

34              dependencies on casts.
