Tom, this discussion brings up something that's been bugging me about the
recommendations for getting more performance out of PG.. in particular the
one that suggests you put your WAL files on a different physical drive from
the database.
Consider the following scenario:

If you are just running the occasional query and want the results placed
into an Excel spreadsheet, you should look at pgAdmin. You run it from

Thanks! Now it is much, much more clear. It leaves me with a few
additional questions though.

We're trying to call a set-returning stored procedure
