# Configuring PostgreSQL for scaling **(FREE SELF)**
2020-07-28 23:09:34 +05:30
2022-07-23 23:45:48 +05:30
In this section, you are guided through configuring a PostgreSQL database to
2021-01-03 14:25:43 +05:30
be used with GitLab in one of our [reference architectures ](../reference_architectures/index.md ).
2020-07-28 23:09:34 +05:30
There are essentially three setups to choose from.
2021-12-11 22:18:48 +05:30
## Standalone PostgreSQL using Omnibus GitLab
2020-07-28 23:09:34 +05:30
This setup is for when you have installed the
[Omnibus GitLab packages ](https://about.gitlab.com/install/ ) (CE or EE),
to use the bundled PostgreSQL having only its service enabled.

2021-12-11 22:18:48 +05:30
## Provide your own PostgreSQL instance
2020-07-28 23:09:34 +05:30
This setup is for when you have installed GitLab using the
[Omnibus GitLab packages ](https://about.gitlab.com/install/ ) (CE or EE),
or installed it [from source ](../../install/installation.md ), but you want to use
your own external PostgreSQL server.

2021-12-11 22:18:48 +05:30
## PostgreSQL replication and failover with Omnibus GitLab **(PREMIUM SELF)**
This setup is for when you have installed GitLab using the
[Omnibus GitLab **Enterprise Edition** (EE) package ](https://about.gitlab.com/install/?version=ee ).
All the tools that are needed like PostgreSQL, PgBouncer, and Patroni are bundled in
the package, so you can use it to set up the whole PostgreSQL infrastructure (primary, replica).
