No, I'm not talking about vacuum as it is intended now, it's only a
process that scans tables to find available blocks/tuples. It is
virtually optional, if it doesn't run, the database will behave just
like now.

No exclusive lock, it's just a reader.

I see this as an optimization issue. If the scanner isn't smart and
loses time scanning areas of the table that have not been emptied, you
go back to the current behaviour.
