That's a seriously OLD OLD OLD version of PostgreSQL.  It has known data
loss and stability bugs, as well as the deadly transaction wrap around
issue.  I'd recommend updating to at least 8.0.x where x is the highest
version currently out yet) or better yet go to 8.1.

You'll get no sympathy from anyone here if or when your 7.1.x database
acts up...

7.1.1?  Egad.  Update to something remotely modern, before it eats
your data.  The list of bugs fixed since then would curl your toes.
See for yourself:

Got to echo this sentiment. I started using Postgresql commercially with version 6.5.  I used Postgresql 7.1 from its release until earlier this year when it ate my data warehouse! Didn't upgrade because the solution was stable for several years then the whole thing blew up with the wraparound problem. I had to work very hard and was very lucky to recover it all. Please upgrade ASAP, it will be unpleasant, you may have to adjust code in some applications because of syntax changes etc., but that's a lot cheaper than losing your data.
