This is horse puckies. Source Forge ran wonderfully on PostgreSQL, and
I can remember when they switched to DB2, it took them over 6 months
just to get keyword searching to work properly. And it was always VERY
slow compared to how fast it had been on PostgreSQL. Find and ask the
guy who built it originally, Tim Perdue. I'm pretty sure he'll back me
up, unless he's under some kind of NDA to not say.

(I never experienced any downtime on sourceforge when it was running on
PostgreSQL, and haven't ever heard crashing as the reason it was
converted to DB2, only that IBM was partnering with them and offered it
for "free" (i.e. they paid them to use it.)
