# Configuring PostgreSQL for scaling
|
|
|
|
|
|
|
|
|
|
In this section, you'll be guided through configuring a PostgreSQL database to
|
|
|
|
|
be used with GitLab in one of our [Scalable and Highly Available Setups](../reference_architectures/index.md).
|
|
|
|
|
There are essentially three setups to choose from.
|
|
|
|
|
|
|
|
|
|
## PostgreSQL replication and failover with Omnibus GitLab **(PREMIUM ONLY)**
|
|
|
|
|
|
|
|
|
|
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, Patroni, and repmgr are bundled in
|
2020-07-28 23:09:34 +05:30
|
|
|
the package, so you can it to set up the whole PostgreSQL infrastructure (primary, replica).

|
|
|
|
|
|
|
## Standalone PostgreSQL using Omnibus GitLab **(CORE ONLY)**
|
|
|
|
|
|
|
|
|
|
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.

|
|
|
|
|
|
|
## Provide your own PostgreSQL instance **(CORE ONLY)**
|
|
|
|
|
|
|
|
|
|
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.
