Running NixOS tests on macOS requires a Linux VM capable of building NixOS VMs. This adds a nix-darwin configuration that provisions an ephemeral QEMU linux-builder with support for aarch64-linux and x86_64-linux builds.

Usage:

nix run github:supabase/postgres#setup-darwin-linux-builder

Enables running NixOS integration tests from macOS development machines (see #1989).

These overlay packages will be removed once the extensions are updated
to use the new `buildPgrxExtension` function.
The previously used version was failing to build:

/build/source/src/common/get_check_data.c: In function 'pgr_SPI_getText':

We cannot use nodejs.libv8 as it is too new for plv8 3.1.
We will be able to use it with plv8 3.2.
dbmate 2.27 is now using a varchar for the version column in the
schema_migrations table.

See amacneil/dbmate#641
Updated nixpkgs, rust-overlay, and nix-fast-build to latest versions.
Removed duplicate substituteInPlace calls that were redundantly applied during previous merge operations. Cleaned up the patch application to avoid duplicate substitutions.

Add -headerpad_max_install_names linker flag to prevent 'install_name_tool:
changing install names or rpaths can't be redone' errors on macOS. This
allocates sufficient header space for install_name_tool to modify the
shared library during post-install processing.
… extensions

Test assertions were inconsistent: expecting {version}.so and {extension_name}-{version}.so
patterns while actual libraries use {lib_name}-{version}.so (e.g. pg_partman_bgw-5.3.1.so,
timescaledb-loader-2.16.1.so). Updated PostgresExtensionTest to accept Optional[str] lib_name
parameter and use consistent {lib_name}-{version}.so assertions throughout.

Added missing timescaledb-loader.so symlink creation and updated the switch script to
maintain both symlinks when switching versions.

Fixes 'Expected timescaledb version 2.16.1, but found timescaledb-loader-2.16.1.so' and
'Expected pg_partman version 5.3.1, but found pg_partman_bgw-5.3.1.so' test failures.
Use overlay instead of passing full nixpkgs-oldstable to avoid exposing
entire old nixpkgs attribute set. Now provides specific packages
(curl_8_4, v8_oldstable) through overlay.
Keep revision support that was accidentally simplified during nixpkgs update.
Restores conditional logic to support building orioledb from specific git
revision hashes instead of only tags.
These files were moved to subdirectories and the old .nix files should be
removed since they were moved to new directory structure with default.nix files.
Remove nixpkgs-go124 dependency since current nixpkgs has Go 1.25.4
which is sufficient for packer. Remove nix-fast-build input as unused
and add follows directives to resolve duplicate dependencies.
Run flake-linter to eliminate duplicate dependencies, and remove unused
cargo-pgrx / rustc versions hashes.
Move pgrouting.nix to pgrouting/default.nix and groonga package to
pgroonga/groonga.nix. Update imports and fix relative paths for versions.json
and patch files.
Replace inline bash script generation with writeShellScriptBin for rustc
wrapper that filters empty postmaster_stub.rs arguments. Apply wrapper only
for pgrx < 0.12 since issue was fixed upstream in pgrx#1435 and pgrx#1441.
Move nixpkgs-oldstable import to a let binding to avoid importing it
three times...
Remove supabase-groonga from global flake packages and import it locally
in pgroonga extension instead. Other components access groonga via
pgroonga.passthru.groonga since groonga is only used by pgroonga.
The supabase-groonga package was moved to pgroonga extension in commit 1f0ed1f,
but Ansible was still trying to install it separately causing build failures.
This reverts commit 55474686405394826ad07a032cbcf0e36a924554.
This reverts commit cfa9bcb92219f391469ae743f95c8856b0a99561.
Remove references to darwin.apple_sdk.frameworks.{IOKit,CoreFoundation}
which have been deprecated in nixpkgs. Disable CGO to avoid Darwin
framework dependencies entirely.
With this new nixpkgs update come gcc 15, which introduced stricter C standard compliance. plpgsql-check fails to build due to this.
To fix the build, we explicitly set the C standard to gnu17.
nix 2.29 doesn't exist in the updated nixpkgs anymore
Replace deprecated system attribute accesses throughout the codebase with
stdenv.hostPlatform.system to resolve Nix deprecation warnings.

Changes:
- Replace inherit (stdenv) system with system = stdenv.hostPlatform.system
- Replace pkgs.system with pkgs.stdenv.hostPlatform.system (55 occurrences)
- Replace system function parameters with stdenv to avoid auto-injection
- Replace final.system in overlay with final.stdenv.hostPlatform.system

Affected files:
- nix/postgresql/generic.nix
- nix/packages/default.nix
- nix/ext/tests/*.nix (16 files)
- nix/packages/lib.nix
- nix/packages/dbmate-tool.nix
- nix/packages/show-commands.nix
- nix/cargo-pgrx/mkPgrxExtension.nix
