Indeed, old habits :)

While the same is true for the hba-file, and ident-file bit, I wanted to
make this point for the postgresql-config-file record as a
whole. Hopefully that makes sense?

Ah, this is probably something I got wrong when documenting the
postgresql-configuration record, I wonder if I copied that from
somewhere else... anyway, I've fixed this now.

Great, I've pushed now with the above changes.
