That's part of pg_wrapper, not core, though.
I'd quite like to see pg_wrapper become part of the PGDG RPMs, but
right now AFAIK it's a Debian-derived-only thing.

Fair point. I'm not a great fan of how those changes affect users, but
I've also seen what too much backward compatibility can do to a
project. (Ref: Java, the Win32 APIs).
If users miss it then it won't explode anything in a way that's
dangerous or harmful, so I won't complain overly. I just wanted to
raise it as a possible concern.
