NAME
DROP CAST - remove a cast
SYNOPSIS
DROP CAST (sourcetype AS targettype) [ CASCADE | RESTRICT ]

PARAMETERS
- sourcetype
- The name of the source data type of the cast.
- targettype
- 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.
