$ niso pull postgres

10x smaller than Docker

This package is 25 MB vs Docker's 250 MB image. That's 10x less disk space, faster pulls, and a smaller attack surface.

PostgreSQL is a powerful, open source object-relational database system with over 35 years of active development. It has a strong reputation for reliability, feature robustness, and performance.

niso packages PostgreSQL as a single binary with its shared libraries -- 25 MB total vs Docker's 250 MB image. Includes psql, pg_dump, pg_isready, and initdb. The database preset provides seccomp filtering, dropped capabilities, and an exclusive data volume with write access restricted to the database process only.
