Tom-
Thanks for the speedy reply.

VACUUM ANALYSE did it.... (doh!...now I feel stupid). I had run VACUUM
and VACUUM ANALYZE from pgAdmin, yesterday. After running it from the
command line now, It's much improved (~ 2-3 secs). I'm now looking
into getting my kernel to increase the SHMAX parameter so I can bump up
the shared buffers some more.
Thanks again for the speedy help, and sorry for the obvious goof.
