It covers eight PostgreSQL distribution and high-availability projects. The chart uses the former repository name `vitabaks/autobase`. This repository has moved to `autobase-tech/autobase`. ![Star History of PostgreSQL distributions and high-availability projects (2026-09-20)](/img/pigsty/star-history-20260920.png) The table compares star growth from the 2026-07-01 baseline through 2026-09-20 (Beijing time). Both snapshots use exact GitHub repository `stargazers_count` totals.
