Oops... I just got it again - right after doing that select count (*),
that *worked*, I tried analyze the same table, and got:

FATAL 2: open of /var/lib/pgsql/data/pg_clog/0980 failed: No such file
or directory

I tried it again, right away, and got the same error, complaining about
02B0 this time

I tried select count (*) again, and it worked.

I restarted the server, did analyze, and it worked too...

Any ideas?
