Might be trickier than it looks though. I think individual autovacuum
worker processes will pick up such settings, but the launcher will not
since it doesn't ever attach to any individual database. So a lot of
undocumented implementation details would matter as to where particular
settings get used ...
Might be better to settle for configuring specific large tables using
per-table vacuum settings, and not sweat the small stuff at a per-DB
level.
