Star History and Growth

The official Star History chart below was fetched on 2026-10-13. It covers eight PostgreSQL distribution and high-availability projects. Server-side caching means a few chart values may be 1–2 stars behind this page’s current snapshot.

The table compares star growth from the 2026-07-01 baseline through 2026-10-13 (Beijing time). Both snapshots use exact GitHub repository stargazers_count totals.
