Well, there is no point in enforcing a rule that something is forbidden
if if was never implied and never documented (the rule here is to be
able to drop custom files into global/, base/ or pg_tblspc.). Postgres
is highly-customizable, I would prefer if features in core are designed
so as we keep things extensible, the checksum verification for base
backup on the contrary restricts things.

So, do we have other opinions about this thread?
