# Configure GitLab using an external PostgreSQL service **(FREE SELF)**
If you're hosting GitLab on a cloud provider, you can optionally use a
managed service for PostgreSQL. For example, AWS offers a managed Relational
Database Service (RDS) that runs PostgreSQL.
Alternatively, you may opt to manage your own PostgreSQL instance or cluster
separate from the Omnibus GitLab package.
If you use a cloud-managed service, or provide your own PostgreSQL instance:
1. Set up PostgreSQL according to the
[database requirements document](../../install/requirements.md#database).
1. Set up a `gitlab` user with a password of your choice, create the `gitlabhq_production` database, and make the user an owner of the database. You can see an example of this setup in the [installation from source documentation](../../install/installation.md#6-database).
1. If you are using a cloud-managed service, you may need to grant additional
roles to your `gitlab` user:
- Amazon RDS requires the [`rds_superuser`](https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/Appendix.PostgreSQL.CommonDBATasks.html#Appendix.PostgreSQL.CommonDBATasks.Roles) role.
- Azure Database for PostgreSQL requires the [`azure_pg_admin`](https://docs.microsoft.com/en-us/azure/postgresql/howto-create-users#how-to-create-additional-admin-users-in-azure-database-for-postgresql) role. Azure Database for PostgreSQL - Flexible Server requires [allow-listing extensions before they can be installed](https://docs.microsoft.com/en-us/azure/postgresql/flexible-server/concepts-extensions#how-to-use-postgresql-extensions).
- Google Cloud SQL requires the [`cloudsqlsuperuser`](https://cloud.google.com/sql/docs/postgres/users#default-users) role.
This is for the installation of extensions during installation and upgrades. As an alternative,
[ensure the extensions are installed manually, and read about the problems that may arise during future GitLab upgrades](../../install/postgresql_extensions.md).
1. Configure the GitLab application servers with the appropriate connection details
for your external PostgreSQL service in your `/etc/gitlab/gitlab.rb` file:
```ruby
# Disable the bundled Omnibus provided PostgreSQL
postgresql['enable'] = false
# PostgreSQL connection details
gitlab_rails['db_adapter'] = 'postgresql'
gitlab_rails['db_encoding'] = 'unicode'
gitlab_rails['db_host'] = '10.1.0.5' # IP/hostname of database server
gitlab_rails['db_password'] = 'DB password'
```
For more information on GitLab multi-node setups, refer to the [reference architectures](../reference_architectures/index.md).
1. Reconfigure for the changes to take effect:
```shell
sudo gitlab-ctl reconfigure
```
