Hi Everyone,
Sorry if I am missing something obvious but I think I have found a bug.
If I perform the following SQL
SELECT MAX(column) FROM table WHERE expression
and there is no match, Postgres returns a record count of 1.
There is no value in max, it is NULL.
Thus trying to perform some "other" tasks based on if a record was
returned or not is proving a little difficult in this instance.
We are using 8.1.9 on Debian.
Thanks for any help you might be able to offer.
