I think most of us see vacuumdb as a historical leftover. We keep it
around in case anyone is still relying on it, but improving it seems
like misdirected effort.
Why isn't your customer using autovacuum? If there are concrete
reasons why that doesn't get the job done for him, it would be more
useful in the long run to work on fixing that.
