I do not like the way that this patch set uses the word "storage".  In
current usage, storage is a thing that certain kinds of relations
have.  Plain relations (a.k.a. heap tables) have storage, indexes have
storage, materialized views have storage, TOAST tables have storage,
and sequences have storage.  This patch set wants to use "storage AM"
to mean a replacement for a plain heap table, but I think that's going
to create a lot of confusion, because it overlaps heavily with the
existing meaning yet is different.

Good point, thank you for noticing that.  Name "storage" is really confusing

for this purpose.

My suggestion is to call these
"table access methods" rather than "storage access methods".  Then,
the default table AM can be heap.  This has the nice property that you
create an index using CREATE INDEX and the support functions arrive
via an IndexAmRoutine, so correspondingly you would create a table
using CREATE TABLE and the support functions would arrive via a
TableAmRoutine -- so all the names match.
