Not that PostgreSQL isn't superior <grin>, but you should also check out
SAP-DB and Firebird (formerly Interbase Open Source), which are full-services
OSS databases.

Correct. The Windows "port" of PostgreSQL is still in development and is
expected to the stable in a few months. If you can wait 'til
August-September for real development, then you're fine.

There are all sorts of reasons not to use ASP, but lack of PostgreSQL
compatibility isn't one of them. You can use ASP + pgODBC if you like.

You are welcome (even encouraged) to charge whatever you want for PostgreSQL
service and development. The license even allows you to charge for
PostgreSQL itself, you just have to look for gullable clients who don't know
they can download it for free. For that matter, you can "roll up" PostgreSQL
as a component of a larger proprietary system and charge for that ... the
license doesn't prevent you. Heck, it's how I make a living.
