You've apparently never used early versions of EnterpriseDB. ;)

Kidding aside, it's apparently been a while since I read that particular 
part of the manual. The error I *was* familiar with was from the 8.0 manual:

"WARNING:  some databases have not been vacuumed in 1613770184 transactions
HINT:  Better vacuum them within 533713463 transactions, or you may have 
a wraparound failure."

Ever since the early days, I've been so paranoid about regular 
vacuuming, I'm probably still a little overcautious.

So, my bad. Having a database down for a few hours isn't exactly 
desirable, but it's certainly not corruption. :)
