DROP TYPE(7)            PostgreSQL 9.5.0 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, 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 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))
