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
