Great question. I think "supposed to" is a bit of a stretch, but I presume
it's the difference between a client connecting and using its connection
information versus an already existing backend process, which is always
going to be "local".
Overall this makes sense, as that checkpoint example above is coming from
the checkpointer background process at 3114981, not the backend process
that happened to trigger it. And 3114981 has no way of knowing the details
of the caller's connection.
FWIW, the patch still applies cleanly to head as of 2/27/2025, so no rebase
needed.
Cheers,
Greg
