Yeah, it moves us much closer to the long-term goal.

Done in v11, with your suggested wording.

Done.

I went with "do not rely on libpq-int.h in dynamic builds of
libpq-oauth", since devs are hopefully going to be the only people who
see it. I've also fixed up an errant #endif label right above it.

I'd ideally like to get a working split in for beta. Barring
objections, I plan to get this pushed tomorrow so that the buildfarm
has time to highlight any corner cases well before the Saturday
freeze. I still see the choice of naming (with its forced-ABI break
every major version) as needing more scrutiny, and probably worth a
Revisit entry.

The CI still looks happy, and I will spend today with VMs and more
testing on the Autoconf side. I'll try to peer at Alpine and musl
libc, too; dogfish and basilisk are the Curl-enabled animals that
caught my attention most.

Thanks!
