It's mentioned in the Red Hat 7.3 release notes.

Anyway, that doesn't help you.  You _might_ be able to reinstall your 
PostgreSQL 7.0 RPM's from your Red Hat 7.1 install media.  Get all the 
postgresql rpm's you have installed off the install media, and put them 
somewhere (I use /root/install as a holding bin for updated and downgraded 
RPMs) and make sure those are the only RPMs in that directory.

Now, you can try:
rpm -Uvh --nodeps --oldpackage postgresql*.rpm

and see what happens.  It _should_ work, even though you will get warnings.

Restart postmaster (/sbin/service postgresql start), dump, stop postmaster, 
then rpm -Uvh to the PostgreSQL RPMs you got with Red Hat 7.3.  Then move 
your old data tree somewhere else, and start the new postmaster.  You should 
be able to restore into it, although some hand-editing of the dumpfile may be 
required.

And next time read the release notes... :-)  Anyway, I certainly feel your 
pain -- I got caught the same way between Red Hat 5.0 and Red Hat 5.1.
