Some odd postgres errors.

Greetings, everyone.

I've got a Postgres system version 7.1-1 on RH 6.2 here, and I'm getting
a whole host of errors.

There is an import program that runs daily from a group of CSV files
uploaded to a server. Since monday, it's been having problems, and I
can't find anything in the import files. Here are some of the errors
below. Some are obvious (invalid float, etC) but the 'bits moved right
off the end of the world' is worrisome, as is Invalid XID in t_cmin..

I've got myself and three others hunting down reasons, but to no avail
yet. We are debating upgrading postgres, although that worries us to, as
this is a production system.

Help ?
