[GENERAL] Cast boolean to text

[Willy-Bas Loos]

Hi,

I've noticed that postgresql  8.1.0 can cast a boolean to text, but version
8.1.5 CAN'T.
Is this a bug or a feature?

as proof, try to run this query:
select 't'::bool::text

On version 8.1.5 one will recieve the error message "can't convert boolean
to text".
