Looks like system catalog corruption to me.  If you're lucky it's only
index corruption and you could fix it with "REINDEX SYSTEM <databasename>"

I seem to recall that you've had a LOT of stability problems in the
recent past.  I'm thinking that there is some underlying problem
with your system -- maybe bad hardware or a nasty kernel bug.
If Postgres were this unstable for everybody, nobody would use it.
