Обсуждение: embedded postgres
Is there an embedded version of postgres that I could compile into a desktop app? I would just use embedded mysql but I don't want to GPL my code or pay them for a licence, plus all of the code was already built for postgres server.

You might want to look into this issue more carefully. If your application just uses a gpl program you don't have to gpl your application since it is a separate application. If you were actually making changes to the database AND distributing it then the changes would need to be gpl'd. Even then there might be a loophole for an embedded modified database server since you wouldn't necessarily be seen as distributing the binaries if the customers didn't have access to them.

Have you looked at small databases that were designed for this sort of thing from the ground up? I'd look at hsql http://sourceforge.net/projects/hsqldb/ for a choice. At 100k, it's a pretty small database engine that seems to get a lot of activity. I'm betting it's not built for 100 users all thrashing it at once, but for imbedded apps, it's hard to say no to a 100k database engine. And, it's got all the BSD goodness you're used to with Postgresql. There are a couple other small databases like this floating around out there as well.
Great! Thats exactly what I want. Now if it's got a SQL engine that won't require me to alter any of my code...

What do you mean by embedded ? Do you have a persistent storage ? Flash or disk ? That would be something you'll need regardless. If you have a Flash secondary storage, then the writes will shorten the life of your flash. Otherwise, PG has a very smal foot print and can be used in most "embedded" environment based on what is embedded today... Your questions are really - do you have persistent storage - do you have sufficient ram (PG not requiring as much as Oracle) - There is also the issue of DB Maintenance (vacuumming) that PG still requires it I think in 7.4 the plan is to make that automatic....

It turns out that SQLite is exactly what I need. Thanks!
