Hi, Jeff
I tried to use the logical tape APIs for hash agg spilling, based on
your 1220 version.
Turns out it doesn't make much of performance difference with the
default 8K block size (might be my patch's problem), but the disk space
(not I/O) would be saved a lot because I force the respilling

Hi,
This patch is currently in "needs review" state, but that seems quite
wrong - there's been a lot of discussions about how we might improve
behavior for append-only-tables, but IMO there's no clear consensus nor
a patch that we might review.

I would have thought that automatic casting would take care of any
