DROP CAST
DROP CAST — remove a cast
Synopsis
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. This is the same privilege required to create a cast.
Parameters
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 have no effect, since there are no dependencies on casts.
Examples
# To remove the cast from type text to type int:
DROP CAST (text AS int);
