# PostgreSQL

Tool · [Standard tools and platforms](https://ecosystem.samcarlton.com/tools)

Also called: Postgres, Postgre SQL, PG, Post gres, psql

A free, [open-source](https://ecosystem.samcarlton.com/open-source) relational [database](https://ecosystem.samcarlton.com/database) known for reliability. Many [hosted](https://ecosystem.samcarlton.com/hosting) services, including [Supabase](https://ecosystem.samcarlton.com/supabase), run on it, so data can move between providers.

**For example:** A startup stores its users and orders in PostgreSQL so it could switch [hosting](https://ecosystem.samcarlton.com/hosting) companies without changing [databases](https://ecosystem.samcarlton.com/database).
