These overlay packages will be removed once the extensions are updatedto use the new `buildPgrxExtension` function.

Updated cargo-pgrx buildPgrxExtension with rustc wrapper to handle emptypostmaster_stub.rs files that cause duplicate symbol errors.(first two filenames are `` and`/build/tmp.*/postmaster_stubs/nix/store/*/bin/postmaster_stub.rs`)pg_jsonschema cargo checks fails on specific versions (0.2.0, 0.3.1, 0.3.3).

Remove deprecated functions that were removed in newer pgrouting versions(_pgr_betweennesscentrality and _pgr_contractionhierarchies).

Improves reproducibility and avoids evaluation-time network access byusing a proper flake input instead of fetchTarball for the older nixpkgsneeded by pg_net and plv8.

…64-darwinVersion 0.19.5 has a dangling pointer issue in src/core.c:177 that causescompilation to fail on aarch64-darwin with newer clang versions. This adds-Wno-error=dangling-assignment to allow compilation to proceed.The flag is restricted to aarch64-darwin only since GCC on Linux doesn'trecognize this warning option.

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

… extensionsTest assertions were inconsistent: expecting {version}.so and {extension_name}-{version}.sopatterns 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_nameparameter and use consistent {lib_name}-{version}.so assertions throughout.Added missing timescaledb-loader.so symlink creation and updated the switch script tomaintain 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 exposingentire 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 gitrevision hashes instead of only tags.

These files were moved to subdirectories and the old .nix files should beremoved since they were moved to new directory structure with default.nix files.

Remove nixpkgs-go124 dependency since current nixpkgs has Go 1.25.4which is sufficient for packer. Remove nix-fast-build input as unusedand add follows directives to resolve duplicate dependencies.

Run flake-linter to eliminate duplicate dependencies, and remove unusedcargo-pgrx / rustc versions hashes.

Move pgrouting.nix to pgrouting/default.nix and groonga package topgroonga/groonga.nix. Update imports and fix relative paths for versions.jsonand patch files.

Replace inline bash script generation with writeShellScriptBin for rustcwrapper that filters empty postmaster_stub.rs arguments. Apply wrapper onlyfor 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 itthree times...

Remove supabase-groonga from global flake packages and import it locallyin pgroonga extension instead. Other components access groonga viapgroonga.passthru.groonga since groonga is only used by pgroonga.

The supabase-groonga package was moved to pgroonga extension in commit1f0ed1f,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 Darwinframework dependencies entirely.

This change adds [crane](https://crane.dev/) support to the existing `pgrx` extension builder, enabling better incremental build performance and caching for `pg_jsonschema` and other pgrx extensions. Crane separates dependency builds from main crate builds, allowing dependencies to be cached independently.The unified `buildPgrxExtension.nix` now accepts an optional `craneLib` parameter. When provided, it uses crane's two-phase build (`buildDepsOnly` + `buildPackage`). Otherwise, it falls back to `rustPlatform.buildRustPackage`. Both paths share the same build and install logic, avoiding code duplication.Crane requires `Cargo.lock` at the source root while `rustPlatform` accepts external `lockFile` paths. The builder handles this by ensuring external lock files are properly accessible during the build process. Crane's `cargoVendorDir` is only used for crane builds to avoid conflicts with rustPlatform's cargo handling.Extensions opt into crane builds by passing `useCrane = true` to `mkPgrxExtension`. All existing build parameters remain compatible with both backends.
