I'm needing to convince my boss that we should upgrade from 7.3.4 to 8.x Postgresql. I've already enumerated the upsides, but now we need to consider the risks...I wonder if anyone can mention/summarize any issues, problems, gotchas, etc. that have happened in anyone's upgrade from 7.x to 8.x ... this would be greatly appreciated. For that matter, if there are any benefits people have seen in addition to what's mentioned on postgres website, this would be good info too.
We are on a Solaris system (including customers with sol 8, 9, and 10), running 7.3.4. Thanks in advance ... and if you would, please cc me at my email address since I'm not subscribed to this alias.
