The darwin sandbox prevents this nix call from accessing `/nix/
store/.links` resulting in a build failure:
```
> error: getting status of '/nix/store/.links': Operation not permitted
```
Thanks to @emilazy for the workaround!
Fixes https://github.com/NixOS/nixpkgs/issues/339808
Found using https://github.com/serokell/xrefcheck, which unfortunately
can't trivially be enforced in CI because we also have the manual markdown
files that need post-processing to be valid
Pscycopg2-binary is normally used in Python development to avoid having to build psycopg2 from source.
In nixpkgs we always want ot build from source whenever possible, but it can still be useful to provide a psycopg2-binary package.
This "fake" package exists to satisfy a dependency on psycopg2-binary, but still use the build from psycopg2.

`importNpmLock.buildNodeModules` returns a derivation with a pre-built `node_modules` directory, as imported by `importNpmLock`.
This is to be used together with `importNpmLock.hooks.linkNodeModulesHook` to facilitate `nix-shell`/`nix develop` based development workflows:
```nix
pkgs.mkShell {
packages = [
importNpmLock.hooks.linkNodeModulesHook
nodejs
];
npmDeps = importNpmLock.buildNodeModules {
npmRoot = ./.;
inherit nodejs;
};
}
```
will create a development shell where a `node_modules` directory is created & packages symlinked to the Nix store when activated.
This code is adapted from https://github.com/adisbladis/buildNodeModules
This patch moves the code snippet which is shown as equivalent to the
example into the actual example block.
Visually, it was not easy to parse that the "equivalent" code piece
belonged to the code snippet that was hidden in the example (which is
collapsed by default).
By moving it into the example block, the "equivalent" piece is hidden by
default as well.

This was supposed to happen in #294504, but the commit was accidentally
left out when splitting off some libpq-related changes. Originated in
#179962, by Sandro.
