## Changes ### pgrx 0.16 Migration - Upgrade pgrx from 0.12 to 0.16 for pg17/pg18 support - Convert all `extern "C"` to `extern "C-unwind"` for pg_guard functions (43 functions across 9 files) - Update GUC registration to use C string literals (`c"..."`) - Update SPI select params from `None` to `&[]` ### pg18 Support - Add pg18 feature flag to Cargo.toml - Add pg18 IndexAmRoutine fields with cfg guards: - amcanhash, amconsistentequality, amconsistentordering - amgettreeheight, amtranslatestrategy, amtranslatecmptype - Add pg18 amestimateparallelscan variant (3 params: Relation, nkeys, norderbys) ### Files Modified - Cargo.toml: pgrx 0.12 → 0.16, add pg18 feature - src/lib.rs: extern C-unwind, GUC c"..." strings - src/index/hnsw_am.rs: extern C-unwind, pg18 IndexAmRoutine fields - src/index/ivfflat_am.rs: extern C-unwind, pg18 fields, amestimateparallelscan cfg guards - src/dag/functions/analysis.rs: SPI params - src/healing/worker.rs: extern C-unwind - src/index/bgworker.rs: extern C-unwind - src/types/vector.rs: extern C-unwind - src/workers/engine.rs: extern C-unwind - src/workers/maintenance.rs: extern C-unwind ### Build Tested - `cargo check --features pg17` passes - `cargo build --lib --features pg17 --release` produces libruvector_postgres.dylib Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
CRITICAL FIX: PostgreSQL 18 added amgettreeheight callback BETWEEN amcostestimate and amoptions, not at the end. This caused all subsequent callbacks to be misaligned by one slot, resulting in segfaults during ORDER BY index scans. Changes: - Move amgettreeheight from end of struct to correct position - Add PG18-specific ORDER BY extraction from scan->orderByData - Clarify comments about PG18 boolean flags vs callbacks Fixes #TBD - HNSW index scan crash on PostgreSQL 18 Tested: ORDER BY embedding <-> '...'::ruvector now works correctly Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
- HNSW_PG18_CRASH_RCA.md: Full root cause analysis, resolution, validation - hnsw-debug-task.json: Original task definition for audit trail Resolves issue where ORDER BY embedding <-> '...' crashed on pg18 Root cause: amgettreeheight callback position misalignment in IndexAmRoutine
- Integration with existing Tailscale ACL tags - Defense in depth security model - PgBouncer configuration for connection pooling - WAL archiving for PITR backup - Health checks and monitoring setup - 90-minute rollout checklist Coordination hub role: metadata, queue state, agent coordination (not primary data store - heavy processing on gmktec-k9)

Summary
extern "C"toextern "C-unwind"for pg_guard functionsProblem
The previous pgrx 0.12 configuration declared pg17 support, but pgrx 0.12 only supports pg14-16. This caused build failures when attempting to build with pg17.
Solution
Upgraded to pgrx 0.16 which properly supports pg17 and pg18. This required:

On macOS, building requires linker flags for PostgreSQL symbol resolution:
