So, I have neglected to do the vacuum on every db for a long time, and this is a very high volume cluster. The db stopped executing requests this morning, and reported: ERROR: database is not accepting commands to avoid wraparound data loss in database "vwuds" So, I did some googling and found I needed to shut down the postmaster, enter single user mode, and vacuum each and every db in my cluster. I did so (even though only about 4 of the 22 databases actually get any appreciable use), but am still hampered by this error. Using 8.3.7 on CentOS. I am really in a bind, obviously, as my system is currently unusable (for what I do with it that is). Thanks in advance, r.b. -- -- Robert W.
