Good Evening,
Before tuning the hardware settings I usually execute an EXPLAIN to see the execution path Postgres uses. A good start to understanding the EXPLAIN functionality is here http://wiki.postgresql.org/wiki/Using_EXPLAIN . Since you're using pgAdmin this is a better tutorial http://www.postgresonline.com/journal/index.php?/archives/27-Reading-PgAdmin-Graphical-Explain-Plans.html . Sometimes using an join instead of a subselect or indexing greatly improves a query even before trying to optimize the default postgres settings.
Thanks
-Mark

tools for tuning PostgreSQL and secondly, it is a tools package for
the Enterprise version of PostgreSQL, so presumably you can get the
support that you presumably paid for.
