You are aware that 8.1.x is up to 8.1.18, right, that's 14 or so
updates you're missing.  Could one of them have fixed a bug that
causes this? Sure.  Look through the changelogs to be sure, but why
not just keep your pgsql version up to date?  It's easier.

Or are you running some redhat version that stays the same number
while getting bugs back ported to it or something? 
That GCC string suggests this is a RHEL3 system, which would have shipped with PostgreSQL 7.3.  Not sure how they got 8.1 onto there, but a later 8.1 is certainly a useful first step to take here, before they get any more corruption from that ancient version when trying to fix things.  Compiling PostgreSQL on RHEL3 from source has some fun challenges; http://markmail.org/message/2bclakrjfxtgwcge#query:+page:1+mid:jhj3yf7zxfmsi22i+state:results covers the main one I'm aware of.  And unfortunately http://yum.pgsqlrpms.org/8.1/redhat/rhel3.0/ seems to be empty, so a source build may be the only good route to get a newer version onto there.
