Sure, PQping is useful for this very specific use case of seeing whether
the server has finished starting up. If someone came with a plausible
use case for a startup script that couldn't use pg_ctl but wanted ping
functionality available in a shell script, then pg_ping could be
provided. But that would also determine what options to provide. For
example, we might not need repeated ping in that case.
But I think people see PQping and will see pg_ping as a monitoring
facility, and I think that's a mistake.
