I have been using postgres 7.0.3 (Solaris 2.9) for the past 4 years without any major problems, until about a month ago. We are now experiencing crashes on the backend (connection lost to backend) while running queries (inserts, etc). Anyway I don't want to make this too technical but I'd just like to understand if maybe I'm running into some sort of limit on the size of the database. My biggest table is currently at 1.5B tuples. Would appreciate if anyone could let me know or is aware of any limits with 7.0 version. Thx, Jose
