# PostgreSQL

PostgreSQL is a powerful, open-source relational database system. This deploys a shared PostgreSQL instance used by many Wild Cloud apps.

## Dependencies

None. PostgreSQL is a standalone infrastructure service.

## Configuration

Key settings configured through your instance's `config.yaml`:

- **storage** - Persistent volume size (default: `20Gi`)
- **port** - Service port (default: `5432`)
- **timezone** - Server timezone (default: `UTC`)

## Usage

Apps that depend on PostgreSQL (such as Immich, Gitea, Discourse, Mastodon, and others) will connect to it at `postgres.postgres.svc.cluster.local:5432`. Each app creates its own database and user via a db-init job during deployment. Root credentials are managed through the secrets system.
