Those extensions don't support building with PostgreSQL 17, yet.
To make sure they will show up as build failures after the next package
upgrade, they all have version checks for their own package version
included.
Since PostgreSQL 9.4 it's possible to build with different uuid
libraries. Eversince, the postgres docs [1] have this to say:
[..] the OSSP UUID library [..] is not well maintained, and is
becoming increasingly difficult to port to newer platforms. [..]
On Linux, OS X, and some other platforms, suitable functions are
provided in the libuuid library, which originally came from the
e2fsprogs project (though on modern Linux it is considered part of
util-linux-ng).
Using e2fs for Darwin was introduced 9 years ago in #8574, which library
to use for Linux was never considered again. Thus, start building with
newer libs now.
As a side effect, we require one less patch if we decide to build with
meson later.

doCheck was enabled in #61395 which does not mention an explicit decision
for "check" instead of "check-world". The latter runs more tests, for example
for contrib modules etc. - but results in higher build times..
Running "nix-build -A postgresql":
- with doCheck = false: 46s
- with checkTarget = "check": 60s
- with checkTarget = "check-world": 75s
/bin/locale doesn't exist on musl and was already effectively disabled
in #228349. However this still leaves the following warning for initdb:
performing post-bootstrap initialization ... sh: locale: not found
By applying the alpine patch to disable locale -a entirely, this warning
will disappear. This will also make one more regression test pass when
testing "check-world" instead of "check", only.
In preparation for the deprecation of `stdenv.isX`.
These shorthands are not conducive to cross-compilation because they
hide the platforms.
Darwin might get cross-compilation for which the continued usage of `stdenv.isDarwin` will get in the way
One example of why this is bad and especially affects compiler packages
https://www.github.com/NixOS/nixpkgs/pull/343059
There are too many files to go through manually but a treewide should
get users thinking when they see a `hostPlatform.isX` in a place where it
doesn't make sense.
