That version is over 6 years old. PostgreSQL 8.0 major version is no
longer supported, see
http://wiki.postgresql.org/wiki/PostgreSQL_Release_Support_Policy. Even
if it was, the latest (and last) minor release from the 8.0 series was
8.0.26, and there was a lot of important bug-fixes between 8.0.1 and that.

That's unlikely a bug. See
http://wiki.postgresql.org/wiki/SlowQueryQuestions. But upgrading is the
first thing you need to do.
