I suspect you mean ALTER DATABASE, rather than table? ;)
I wonder if we don't want this to be a slightly more generic
facility. E.g. pg_upgrade has the same need. Perhaps we whould
superuser-only connection-establishment only option that allows
connecting to a database even if datallowconn = false, and then
additionally allow to pass connection arguments to
BackgroundWorkerInitializeConnection()? It seems fairly reasonable to
want to establish different GUCs via normal GUC-y mechanisms when
establishing a bgworker connection...
