There are also a lot more PostgreSQL developers and users interested in
UNIX systems. While there appear to be lots of PostgreSQL users on
Windows now they don't seem to be very frequent contributors,
particularly active on the mailing lists, etc.
That's going to reduce the rate of PostgreSQL's improvement on Windows,
especially given how generally unpleasant the platform is to develop on*.

The appropraite setup also depends on your controller's performance
characteristics, your particular workload, etc. If things are busy
enough you might even want to look at using tablespaces to split busy
tables on to separate volumes.

wacky problems in C++ code. gdb is OK for C, but awful for C++. It often
seems to be necessary to have two systems - a Linux one for valgrind and
everything else, plus a Windows one for VC++'s debugger.
