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.
