NAME
DROP_TYPE - remove a data type
SYNOPSIS
DROP TYPE [ IF EXISTS ] name [, ...] [ CASCADE | RESTRICT ]
DESCRIPTION
DROP TYPE
removes a user-defined data type. Only the owner of a type can remove it.
PARAMETERS
IF EXISTS
-
Do not throw an error if the type does not exist. A notice is issued in this case.
name
-
The name (optionally schema-qualified) of the data type to remove.
CASCADE
-
Automatically drop objects that depend on the type (such as table columns, functions, and operators), and in turn all objects that depend on those objects (see
Section 5.14).
RESTRICT
-
Refuse to drop the type if any objects depend on it. This is the default.
EXAMPLES
To remove the data type
box:
-
DROP TYPE box;
COMPATIBILITY
This command is similar to the corresponding command in the SQL standard, apart from the
IF EXISTS
option, which is a
PostgreSQL
extension. But note that much of the
CREATE TYPE
command and the data type extension mechanisms in
PostgreSQL
differ from the SQL standard.
