pg_audit handles this (it is one of the specific goals of that project,
in fact) and the case where modifications are done inside of DO blocks
and PL code. Further, it provides a great deal of additional
flexibility.
What we need here is better logging/auditing capabilities in core.
Improving the documentation for the back-branches is good but doesn't
address this use-case. It's unfortunate that we don't have a better
answer at this time.
Thanks!
