Re: "Custom" records?

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?
