Hi!
Hannu, we'd already made an attempt to extract the TOAST functionality as API
and make it extensible and usable by other AMs in [1], the patch set was met calmly
but we still have some hopes on it.
Michael, glad you continue this work! Took patch set for review.
[1] Pluggable TOAST

Hi Michael
I'll take a look at the patch set.
While digging around in the TOAST code did you have any ideas on how
one could extract the TOAST APIs in a way that they can be added in
Table Access Method definition ?
Not all TAMs need TOAST, but the ones that do could also be the ones
that still like to do something different when materializing toasted
values.
And TOAST is actually a nice abstraction which could be used as basis
for both offloading more columns into separate forks and files as well
as implementing some kinds of vectored, columnar and compressed
storages.
