DROP TYPE(7)                      PostgreSQL 14.15 Documentation                     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,
           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.

SEE ALSO
       ALTER TYPE (ALTER_TYPE(7)), CREATE TYPE (CREATE_TYPE(7))
