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 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.
