Postgres, its extensions, and everything loaded into the postgres process stay on nixpkgs fb7944c, glibc 2.40, through a new nixpkgs-pg17 input. After a glibc bump, Postgres warns that the collation version stored in each database differs from the running one. The main nixpkgs input moves to the nixos-26.05 channel so it can be updated on a schedule. All PG outputs keep their drvPath on x86_64-linux, aarch64-linux, and aarch64-darwin: psql_*, every extension, postgresql_*, postgres-env, site-env, extension catalogs, gatekeeper, and groonga. Also: - nix-darwin follows its nix-darwin-26.05 branch to match nixpkgs. - ext tests import QemuMachine, since 26.05 dropped test_driver Machine. - hstore_copy_binary writes inside the data dir, not a shared /tmp path that collides across unsandboxed darwin builds.

- Rename nixpkgs-pg17 to nixpkgs-pg, since it also builds pg15. - Import the main nixpkgs without overlays. Only nixpkgs-pg needs rust-overlay, cargo-pgrx, cgal, and the oldstable curl and v8. - Build site-env from the main nixpkgs, so supautils and gatekeeper pick up updates. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
gatekeeper loads into postgres without an RPATH, like supautils, so site-env and postgres-env now share one build from the main nixpkgs. pg_regress and pg_isolation_regress are test clients. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Drop the nixpkgs-pg pin. Postgres and its extensions build from the nixos-26.05 nixpkgs too, which moves them to glibc 2.42. pg_net builds against the main curl instead of curl_8_6 from nixpkgs-oldstable. Versions before 0.20.4 need -DCURL_DISABLE_TYPECHECK, since newer curl headers break their multi.h include. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

glibc 2.42 re-versions cfgetospeed, so the bundled libncursesw needed GLIBC_2.42 and failed on Ubuntu 24.04. The bundle now ships an ncurses that resolves the GLIBC_2.17 symbol at runtime. Also fix the two nixos-26.05 deprecation warnings in groonga: a nested buildInputs list and the xxHash rename. Refs: MPG-1323 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
