Joel,
I don't have an answer for this, but I do have a question.
I couldn't find any way to get a median native in PostgreSQL, did you write
a median function or some such? If so, would you be willing to share it?
Thanks,
Peter Darley

Before asking this, I suspect that the answer is no, but I'll ask anyway.

Is there a way to return a completely custom column/row record from a
plpgsql function?

I'd want a function "Descriptives(int)" with results to looking like the
below when SELECT:ed :

measurement | value
------------+------
Mean | 15.8
Median | 16.0
Std.dev | 0.8
Max | 38.0
Min | 0.0

If not possible in plpgsql, is there a workaround while still not having
an external program fetching a lot of data from the DB to do the
calculation?
