This is database corruption and extremely unlikely to be a bug in
the current maintenance release of 8.3.  Please read the following
page and post with more information to the pgsql-general list:

http://wiki.postgresql.org/wiki/Guide_to_reporting_problems

Your first step, though, should be to stop the PostgreSQL service
and make a complete copy of the data directory and all its
subdirectories, and plan on keeping that until at least a few weeks
after the issue is resolved.
