Stackage Nighly recently upgraded their version of hackage-db from 2.1.0
to 2.1.1. 2.1.1 had a compatibility fix for Cabal 3.4 [1]. However it
did not increase the version bound on Cabal nor fails to compile with
Cabal 3.2, so Stackage was able to update it.
Unfortunately hackage-db with Cabal 3.2 causes observable issues [2]
in cabal2nix, so we need to downgrade it for all compilers that still
ship a Cabal version < 3.4.
Also ideally we should update the constraints for hackage-db 2.1.0 and
hackage-db 2.1.1 on hackage. See also [3].

These attribute names were converted into aliases in the following
changes:
* 62733b37b4
* https://github.com/NixOS/nixpkgs/pull/104776
cabal2nix-unstable has been updated to be aware of these changes in
7a9080d774, so these aliases should no
longer cause issues when evaluating with `allowAliases = false`.
While diagrams-lib 1.4.4 doesn't per se require us to update any
diagrams lib to 1.5.0 it would require monoid-extras 0.6 which would
force us to update diagrams-core to 1.5.0, thus breaking
haskellPackages.diagrams.
Since we can just keep the patch we fetch and downgrade to 1.4.3, we
can continue sitting out the slow update cycle of the diagrams universe.
This reverts commit 52d69816b0.
Unfortunately there is no way to update to monoid-extras 0.6 yet without
marking some packages as broken. The issue is that not all diagrams*
packages have had an update adding support for GHC 9.x yet (which would
also include monoid-extras 0.6 support). The only alternative to pinning
diagrams* and monoid-extras would be to have mismatched versions between
them which always causes issues with haskellPackages.diagrams.
Note that this commit re-introduces some build failures which are to be
fixed in a follow-up commit.
They are not an exposed part of haskellPackages per se, so we shouldn't
list them in nix-env. Additionally this should prevent the failed lldb
build from cluttering our jobset output.
Seems like the monoid-extras situation wasn't as bad as I thought and
some new releases in the meantime make every diagrams package we had
working previously work again.
* haskellPackages.monoid-extras: 0.5.1 -> 0.6
* haskellPackages.diagrams-lib: remove now unnecessary patch
* haskellPackages.namespace: jailbreak to build with new monoid-extras
