Yes, sorry for coming late at the party here.  What I meant previously
is that I did not find the version published at [1] to be natural with
its structure to define an executor callback which then calls a
callback for table AMs, still I get your point that it would be better
to try to avoid unnecessary fsync calls on partitions where no tuples
have been redirected with a COPY.  The version 1 of the patch attached
at [2] felt much more straight-forward and cleaner by keeping all the
table AM callbacks within copy.c.

This has been reverted as of f5db56f, still it seems to me that this
was moving in the right direction.
