Description of changes

postgresql14Packages.promscale_extension breaks with:

Error:
  0: `pgx-0.6.1` shouldn't be used with `cargo-pgx-0.7.4`,
  please use `pgx = "~0.7.4"` in your `Cargo.toml`.

However, pinning cargo-pgx to 0.6.1 via the following

buildPgxExtension.override { cargo-pgx = cargo-pgx_0_6_1; }

does not work either, because the build then fails with:

thread 'main' panicked at /build/promscale_extension-0.8.0-vendor.tar.gz/proc-macro2/src/fallback.rs:756:9:
  "__mbstate_t_union_(unnamed_at_/nix/store/ij144ma6vs8acil8r9hgr8xkb1dp9azg-glibc-2_39-5-dev/include/bits/types/__mbstate_t_h_16_3)" is not a valid Ident

This seems to be related to rust-lang/rust-bindgen#2312, which indicates that this is a problem with newer LLVM / clang toolchains.

At the same time th upstream package is deprecated / archived since the 2nd of April 2024. Additionally this package is unfree and thus very unlikely to be forked. Since we can't expect this to be fixed, the only sensible thing to do is to remove the package.

Once this package is removed, there is no user of the buildPgxExtension infrastructure left. pgx was renamed to pgrx
and we still have newer versions of pgrx in nixpkgs. So this essentially just removes old, now unused versions.

This seems to be related to [1], which indicates that this is a
problem with newer LLVM / clang toolchains.

At the same time th upstream package is deprecated / archived since
the 2nd of April 2024 [2]. Additionally this package is unfree and
thus very unlikely to be forked. Since we can't expect this to be
fixed, the only sensible thing to do is to remove the package.

[2]: timescale/promscale#1836
pgx had been renamed to pgrx in April 2023 already [1]. Newer versions
are already in nixpkgs as pgrx. Since the previous commit removed
the only remaining instance of a package still depending on
pgx 0.6.1, we can now remove all of buildPgxExtension and cargo-pgx.

LGTM. Thank you!
Let's wait a bit for the maintainers.

LGTM. Certainly it doesn't make sense providing abandonware.
