# PostgreSQL

PostgreSQL is our most used relational database system in the Lab.

The [Wikipedia article for Postgres](https://en.wikipedia.org/wiki/PostgreSQL) gives a fairly thorough overview.

One of the higlights of the PostgreSQL community is their wealth of documentation at <https://www.postgresql.org/docs/manuals/>. Their manual is hence a good read, even though it is 2000+ pages long. Reading that manual will give you a better introduction to Postgres than our documentation could cover.

The PostgreSQL team uses <https://git.postgresql.org/gitweb/?p=postgresql.git> as their central Git repository.
