If you do regular VACUUM frequently enough, you shouldn't ever need to do a FULL one anyway.Basically we have some background process which updates "table1" and we
don't want the application to make any changes to "table1" while vacuum.
Vacuum requires exclusive lock on "table1" and if any of the background or
application is ON vacuum don't kick off.
