I understand that you are for documenting the timing of permission checks,
but not in the postgres_fdw documentation. However, this is the only occasion
where the user might notice unexpected behavior on account of the timing of
permission checks. Other than that, I consider this below the threshold for
user-facing documentation.
I'm ok with just doing nothing here, I just wanted it discussed in public.
