If I understood what VACUUM light does, I do not think that people
will need to actually do the conventional VACUUM as often anymore.
I understood, that VACUUM light makes outdated tuple heap space available
for reuse, and removes the corresponding index entries.
It does not make space available to other tables or the OS,
but most other DB's do not do that eighter.
The conventional VACUUM would then be something you do as part of a DB
reorganization (maybe once every month or so).
