I don't remember the developers ignoring data corruption bugs even back 
in the 6.x series (which is pretty much where the project started - the 
Postgres95 stuff and before were mainly academic systems). As far back 
as I can remember (which is 6.x) if it's been found, it's been fixed.

Performance (particularly on v.simple web-app type queries) was not PG's 
strong point. I think you'd be hard put to find anyone (even then) who 
said it was.

Perfectly reasonable choice. That's why Oracle built such large business 
from databases.


Coming up on next week's discussion group:
- Tony Blair: Can he really lead Labour to victory?
- Y2K: Do we still have time to prepare?
- Can RedHat 5 displace Windows on the desktop?
