Tell me how that works out. I have a few tables with more than 100M
records in them but only the last 5M (by time -- so it's well clustered)
or so are in active use.

Looked at inheritance, but it seems to do a select against the structure
anyway. Using partial indexes with a common datastore seems to work much
better, until VACUUM runs...
