DROP TYPE

Description

Drops a user-defined data type.

Precautions

Only the type owner or a user granted with the DROP permission can run the DROP TYPE command. System administrators have this permission by default.

Syntax

DROP TYPE [ IF EXISTS ] name [, ...] [ CASCADE | RESTRICT ]

Parameters

  • IF EXISTS

    Reports a notice instead of an error if the specified type does not exist.

  • name

    Specifies the name (optionally schema-qualified) of the type to be dropped.

  • CASCADE

    Automatically drops the objects (such as fields, functions, and operators) that depend on the type.

    RESTRICT

    Refuses to drop the type if any objects depend on it. This is the default action.

Examples

See Examples in "CREATE TYPE."
