We're a hoster, so usually each database belongs to a different
customer. Each customer can have a "get a dump of our database daily"
dump. Also, restoring a single db is simpler when you got a dump of it.

Agreed, for a classical db server this could be better. We need the
per-db dumps, so pg_dump performance tuning would be nice. It's quite
slow currently. Someone got hints what to do against that?
