While this reverts regressions, this has to cause "new" regressions.
The problem here is that the previous regressions are relatively recent,
still, and the previous regressions are ***much worse*** than the slight
newer regressions that fixes the older regressions.
Note that this is not regressing the packages that are "newly"
regressing prior to the versions they were beforehand. They are now
currently pinned in a pessimistic manner, to correctly fix the problems
in the way that was initially intended.

Except:
- Instances in documentation, because people in older versions
can't switch to nixfmt yet due to it having pointed to nixfmt-classic
before
- In code that runs based on a CI Nixpkgs version, which is also a bit
older still
- In update script shebangs, because many of them don't pin Nixpkgs, and run
with whatever is in NIX_PATH (and it's not easy to fix this, see
https://github.com/NixOS/nixpkgs/issues/425551)
This was done with booxter’s fantastic [nix-clean-apple_sdk] tool,
simply modified to look for `libobjc` rather than the existing list he
already used in <https://github.com/NixOS/nixpkgs/pull/398707>. Some
manual work was applied, including cleaning up a string interpolation
in the terrifying MacVim derivation, stray comments, empty lists,
function parameters, and `inherit`s, including all of the references in
`all-packages.nix`.

They are not doing anything right now. This is in preparation for their
complete removal from the tree.
Note: several changes that affect the derivation inputs (e.g. removal of
references to stub paths in build instructions) were left out. They will
be cleaned up the next iteration and will require special care.
Note: this PR is a result of a mix of ugly regex (not AST) based
automation and some manual labor. For reference, the regex automation
part was hacked in: https://github.com/booxter/nix-clean-apple_sdk

Format all Nix files using the officially approved formatter,

This is the next step of the of the [implementation](https://github.com/NixOS/nixfmt/issues/153)
of the accepted [RFC 166](https://github.com/NixOS/rfcs/pull/166).
This commit will lead to merge conflicts for a number of PRs,
up to an estimated ~1100 (~33%) among the PRs with activity in the past 2
months, but that should be lower than what it would be without the previous
[partial treewide format](https://github.com/NixOS/nixpkgs/pull/322537).

By replacing upstream's pg_config binary with a shell script, we:
- gain the ability to run pg_config easily when cross-compiling,
- can remove the fake pg_config in the default output,
- can remove the pg_config wrapper script dealing with special cases.
Some 20 years ago, pg_config *was* a shell script upstream, too. It was
changed to a binary, when it was made "relocatable", so it would return
paths depending on the location of the "postgres" binary. However, this
is exactly the thing that just hurts us in nixpkgs - we don't want those
paths to change, we want them to always point at the right outputs. By
writing the script ourselves, this becomes a lot less painful.
This approach means more lines of codes, but all of them are dead simple
and we have a lot less complexity overall.
Additionally, pg_config is now made a separate derivation, only exposed
as "postgresql.pg_config". This has the nice side-effect, that all users
of postgresql and libpq in nixpkgs must be very *explicit* about their
dependency on pg_config. This gives a lot more visibility into the state
of affairs regarding pkg-config support for libpq, which ultimately is
the much better solution.
