NAMEDROP_TYPE - remove a data type SYNOPSISDROP TYPE [ IF EXISTS ] name [, ...] [ CASCADE | RESTRICT ] DESCRIPTIONDROP TYPE removes a user-defined data type. Only the owner of a type can remove it. PARAMETERSIF 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 5.15).
RESTRICT Refuse to drop the type if any objects depend on it. This
is the default.
EXAMPLESTo remove the data type box: DROP TYPE box; COMPATIBILITYThis 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 ALSOALTER TYPE (ALTER_TYPE(7)), CREATE TYPE (CREATE_TYPE(7))
