boolean type cast

Hi,

I found a minor glitch in the documentation for 8.1 where it talks about
boolean data type.

Here is what the documentation says:

"Tip:  Values of the boolean type cannot be cast directly to other types
(e.g., CAST (boolval AS integer) does not work)."


It is true for pre-8.1. As for 8.1, however, boolean type cast works:

=# select true::int;
 int4
------
    1
(1 row)



regards,
