It would be Really Nice if it could draw in the verbose stats as to
what the VACUUM did...

e.g. - to collect some portion (INFO?  DETAIL?  I'm easy :-)) of the
information that PostgreSQL generates at either INFO: or DETAIL:
levels.

the top of your voice, everyone just stares at you. If you do the same
thing on an aeroplane, why does everyone join in?
