About the project
A PostgreSQL extension providing a PRISM index for high-performance approximate nearest neighbor vector search, with RaBitQ quantization and SIMD distance computation. It is compatible with pgvector columns and targets large-scale vector workloads.
Useful for
- Build a PRISM index on an existing pgvector table without rewriting data
- Run ANN queries over 100M+ vectors with tunable recall via prism.nprobe
- Replace an HNSW index with PRISM and verify the planner picks it via EXPLAIN

The star-growth assessment does not verify whether the project is safe to run.
Stars per day
Bars show stars per UTC day; the line is a moving average of available history. Gaps mean missing data, not zero growth. Today's bar is incomplete. Red marks spike days.
Why it’s trending
- Star-counter measurements on 2026-10-14 (UTC), 13:28–14:22: 110 → 137 stars (+27). This is the change over that interval.
- Estimated end-of-day forecast: about +45 stars, using observed gains and the previous day.
- Before this, the repository barely got any stars — about 0 per day.
- Hacker News: “Pg_vectorsearch: An index that is faster than pgvector's IVFFlat and HNSW” — 80 points, 2 h ago.
Measured growth: the last 7 completed days
New stars over 7 days: 55.

Star trust
Growth looks organic: forks and discussion are in line with active projects, and stars arrive unevenly, the way people give them.
These are heuristics, not a verdict: we judge by the repository’s behavior, not by a list of stargazers.
