DROP TYPE(7)                     SQL Commands                     DROP TYPE(7)

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

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