nice, if you want to store pics, I suggest filesystem - with some nice
schema to do it.
The way I do it, is using md5 of pics/other data, and three level of
directories to lead you to the right file on disc.
It is dead easy to implement, and much faster than bytea in DB. (at
least on linux, I wouldn't hold my breath so much for ntfs, but you
never know).
100 connections is quite a bit, so you need a bit of memory. It also
depends on the actual queries, and schema.
If you have any questions about that, and performance - we are here to help.

just like scott said,
Make sure to either turn off anti-virus, or tell it to stay away from
postgresql. (which leaves your machine quite vulnerable, so make sure
to secure it well).
