rUv 625f16c744 fix(hnsw): resolve segfault with parameterized queries (Issue #141) ... This commit fixes a critical P0 bug where HNSW indexes on ruvector columns would crash PostgreSQL with a segmentation fault when using parameterized queries (prepared statements, ORMs, application drivers). Root Cause: - Query vector extraction failed for parameterized queries - Code fell back to zero vector without validation - Zero vector caused segfault during HNSW search Changes: - Add multi-method query vector extraction pipeline 1. Direct RuVector::from_polymorphic_datum() 2. Text parameter conversion for parameterized queries 3. Validated varlena fallback with dimension checking - Add query_valid flag to track extraction success - Add validation before search execution: - Reject empty/invalid query vectors with clear errors - Reject all-zero vectors (invalid for similarity search) - Validate dimension match between query and index - Apply same fixes to IVFFlat for consistency Testing: - Added regression tests for parameterized queries - Added tests for zero vector error handling - Added tests for dimension mismatch errors - Added 384-dimension production-scale tests Fixes: #141 See: docs/adr/ADR-0027-hnsw-parameterized-query-fix.md Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>		2026-01-28 16:34:42 +00:00
