I am told pop_stddev(integer) does not exist and explicit type casting
may help. I'll be reading up on that in the next few minutes and see if
I can get this working. I know why the aliases were a problem or would
have been a problem too, the first word in every one of them that don't
work now was population with a blank space following it so psql probably
thought this idiot is trying to hang four aliases on a single string so
I got a yellow card for my efforts. The pop_stddev() is an aggregate
but one I've never used before inside psql or sql.
