First, you should consider to upgrade your PostgreSQL server to a newer
version, at least to 7.2.8 which fixes some critical bugs.

But it will be much better to upgrade to current 8.1 version, as I think
that your problem is caused by index bloat, and indices are handled much
better in 8.1.

Try recreating your indices using REINDEX command.

HTH,
Markus
