Side note re limited to non-Windows by postgresql.
I've often run cygwin postgresql and, while it takes a few minutes to setup, has run fine for me. I've read elsewhere of people having stability problems with that env but have not encountered any on my end. I don't know if the stability problems with cygin/postgres have been resolved or if my db apps just haven't stressed postgres enough to hit a cygin/postgres instability. I ack that the native flavor postgres should be much faster than cygin indirection flavor, but whether that's a problem or not is dependent on amount of data and desired response time. Just a note. And, yes, native postgres 8.x should be out shortly.
Cheers, Heitzso
