Thanks Scott and Tom.
Yes. I know, I know that I need to upgrade :-)
What would be the newer version of pgsql (I mean a bit higher version of my current version) that provides that
capabilityof telling me what the duplicated key was ?
Migration is always a challenge, especially I'm not sure if I will have any unexpected hiccups when I dump my whole DB.
Ialso need to upgrade the OS. My first priority is to get this problem fixed so that my users will stop IM, email or
callme.

If you were using a more modern version of pgsql, it would tell you what the duplicated key was ;-). So maybe you
couldtry loading the dump file into something newer as a means of debugging the problem.
