Issue found on page 'Enum Data Type': Would be good to mention you use anonymous ENUM types in CAST operations (without CREATE TYPE)

[rpbouman]

The ENUM data type page currently suggests you need to create the ENUM type explicitly using CREATE TYPE.

However, it is possible to use anonymous ENUMs in CAST expressions, in which case no CREATE TYPE statement is required beforehand:

SELECT 'ok'::ENUM ('sad', 'ok', 'happy') as mood

It would be good to mention this syntax.
