Re: replication, availability of my server

I think I remember reading in 7.1 there was a bug in VACUUM ANALYZE that can
corrupt indexes, eg put multiple values into a unique pkey index.

I think that REINDEX to rebuild the indexes is probably what you want, but I
would do a dump first to make sure you have all the data saved in case
things go wrong.

Please note: This is an opinion, I have never had to recover from this
specific problem myself.
