# 6. Limitations

The following PostgreSQL versions are currently supported:

- 11
- 10
- 9.6
- 9.5
- 9.4

Other versions are usable but not fully integrated in all components. This might make additional manual tuning necessary.

Packages for all PostgreSQL versions are installable via the apt.postgresql.org repository on Debian/Ubuntu, and yum.postgresql.org on RedHat/CentOS. Please see https://apt.postgresql.org/ for more information.
