Re: Aggregate Function (AVG) not calculated correctly

No, you haven't: where are the table declarations?

But I'll take a guess anyway: you declared "distance" as int2, didn't
you?  AVG(int2) currently uses an int2 accumulator, and you're suffering
overflow.  Try "AVG(distance::float8)" instead.

We've changed AVG() to use a numeric accumulator for 7.1, but that
won't help you today.
