Don, I see Bruce's proposal as implementation details within the sotrage
manager. In fact, we should probably implement the tablespace commands
with an extention of the smgr api. One different smgr I've been thinking
a little about is the persistent RAM smgr: I've heard there's some
new technologies coming up that may make large amounts cheaper, soon.
And there's always PostgreSQL for PalmOS, right? (Hey, IBM's got a Pocket
DB2, why shouldn't we?)
