Is there a guide to use PostgresSQL as alternative to MariaDB/MySQL in OpenStack?

[Larry Sevilla]

Hi,

I'm studying OpenStack Zed using Ubuntu 22.04 with the following guides:

https://docs.openstack.org/install-guide/

And I have successfully installed OpenStack services and tested Horizon.


But the guide uses MariaDB/mysql.
https://docs.openstack.org/install-guide/environment-sql-database-ubuntu.html


Is there a guide for PostgreSQL?
