The problems I'm having with postgresql are mainly in the area of blobs. I need to store several binary objects, generally in the 800-2400 byte range, and I also need to store text messages sent by people, and I have to deal with truncation and such to stay within the 8k row-size limit. I've heard I can update the blocksize to 32k, but then I've read this has other negative impacts and that 7.1 solves it anyway -- but when will that be stable and ready? Anyway, I'm giving them both a quick test, primarily with regard to transactions and blobs. I can report back what I learn, but it will only be at a testing level, and I'd prefer to hear from production users. David
