Fortunately the servers use 2G or 4G of memory, only my test
machine had 1G, as I believe I precised in a message; so I'm
definitely going to use Mark's advices to enlarge a lot the
shared buffers. Btw, what about sort_mem? I have seen it only
little referenced in the documentation.
Also, I'd still be interested in comments on the result of pmap
showing around 450M of "private memory" used by pg, if anyone can
share insight about it. Though most people seem freebsd-oriented,
and this might be very much linux-centric.
