I dare say that if we had some documentation around what to expect and how
to deal with it, for our own tools as well as external ones, then maybe we
wouldn’t be in this situation in the first place. Clearly ALTER SYSTEM and
the pg_basebackup modifications had different understands and expectations.

I haven’t looked at the code patch at all, just to be clear. That said, if
you’re comfortable with it and it’s in line with what we document as being
how you handle pg.auto.conf (for ourselves as well as external tools..),
then that’s fine with me.

Thanks,

Stephen
