Yeah, I'd be happier with "pg" than "pg_ctl" as well. But it's so short that I wonder if some other software has already adopted it.
So it's been removed from posix, but not unlikely to be around. For example, I see it on a server with Debian 9 (Stretch) or Ubuntu 16.04 which is still well in support (but not on a RedHat from the same era).
