I like the syntax, but what I really want to know is how well this is
going to work with the query planner.  The current 8.x table
partitioning mechanism has a lot of causes more problems
than it solves unless you are willing to strictly control how you
query the tables...I usually end up rolling my own.

Are you confident that what you propose will integrate well with the
planner and produce (as much as possible) fully optimized queries?
