feat: add VectorChord extension for PG17#10
Merged
Conversation
Dockerized utility (tools/pgrx-hash/) that computes Nix SRI hashes for new cargo-pgrx versions. Uses linux/amd64 Docker container so ARM machines can produce correct x86_64 hashes via QEMU. Usage: ./tools/pgrx-hash/run.sh <pgrx-version> <rust-version>
Switch from mounting repo files directly to writing results to a local output directory. Use nixos/nix base image with sandbox disabled instead of runtime Nix install on Ubuntu, fixing QEMU timeout on ARM hosts.
Add VectorChord 1.1.0, a scalable disk-friendly vector search extension. Requires pgrx 0.17.0 and Rust 1.90.0 — both bootstrapped via the pgrx-hash tool and added to cargo-pgrx packages.
Load pgvector, kilobase, and vchord in CI health checks to verify extensions are built correctly and can be created in PG17.
