Re: [luciddb-users] multiple databases

There is no technical reason; the underlying components are already 
designed for it in Fennel.  We do need to figure out how some of the 
newer features (warehouse labels and backup/restore) intersect with this 
work, and also decide on the best way to support the "movable" use case 
you mention (for that, a correspondence between logical schema and 
physical tablespace is desirable, whereas for general purposes it's nice 
to keep physical and logical containment independent).
