My original request was to change to INFO, which is what vacuum proper does at
vacuum_open_relation(). I realize that still means that new work item handlers
would have to do the LockOid, try_open dance - maybe it could be factored out.
I noticed this on multiple servers immediate after changing a nagios script to
look for all ERRORs (rather than a specific list of log_messages) and for a
longer time period.

Should it be done in an AtCommit hook or something like that ?
