DROP TYPE()			 SQL Commands			   DROP TYPE()

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  ta‐
	      ble columns, functions, operators).

       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	 stan‐
       dard, apart from the IF EXISTS option, which is a PostgreSQL extension.
       But note that the CREATE TYPE command and the data type extension mech‐
       anisms in PostgreSQL differ from the SQL standard.

SEE ALSO
       CREATE TYPE [create_type(7)], ALTER TYPE [alter_type(l)]
