I remembered another reason why v12 should be a cutoff: it's where
we started to use snprintf.c everywhere. In prior branches, there'd
be a lot of complaints about sprintf elsewhere in the tree.
So I pushed (1), but on the way to testing (2), I discovered a totally
independent problem with the 13.0 SDK in older branches:
In file included from ../../../src/include/postgres.h:46:
In file included from ../../../src/include/c.h:1387:
In file included from ../../../src/include/port.h:17:
In file included from /Library/Developer/CommandLineTools/SDKs/MacOSX13.0.sdk/usr/include/netdb.h:91:
In file included from /Library/Developer/CommandLineTools/SDKs/MacOSX13.0.sdk/usr/include/netinet/in.h:81:
/Library/Developer/CommandLineTools/SDKs/MacOSX13.0.sdk/usr/include/sys/socket.h:471:1: error: expected ';' after top level declarator
__CCT_DECLARE_CONSTRAINED_PTR_TYPES(struct sockaddr_storage, sockaddr_storage);
This is apparently some sort of inclusion-order problem, which is probably
a bug in the SDK --- netdb.h and netinet/in.h are the same as they were in
SDK 12.3, but sys/socket.h has a few additions including this
__CCT_DECLARE_CONSTRAINED_PTR_TYPES macro, and evidently that's missing
something it needs. I haven't traced down the cause of the problem yet.
It fails to manifest in v15 and HEAD, which I bisected to
98e93a1fc93e9b54eb477d870ec744e9e1669f34 is the first new commit

Clean up messy API for src/port/thread.c.
The point of this patch is to reduce inclusion spam by not needing
to #include <netdb.h> or <pwd.h> in port.h (which is read by every
compile in our tree). To do that, we must remove port.h's
declarations of pqGetpwuid and pqGethostbyname.
I doubt we want to back-patch that, so what we'll probably end up with
is adding some #includes to port.h in the back branches. Bleah.
Or we could file a bug with Apple and hope they fix it quickly.
(They might, actually, because this SDK is supposedly beta.)
