# PostgreSQL

Database clusters via CloudNativePG operator.

## Quick Reference

| Property | Value |
|----------|-------|
| **URL** | `tcp://pg.ops.eblu.me:5432` |
| **Metrics** | `http://cnpg-metrics.tail8d86e.ts.net:9187/metrics` |
| **Namespace** | `databases` |
| **Clusters** | `blumeops-pg`, `immich-pg` |
| **Operator** | CloudNativePG |

## Databases

| Database | Cluster | Owner | Purpose |
|----------|---------|-------|---------|
| miniflux | blumeops-pg | miniflux | [[miniflux]] feed data |
| teslamate | blumeops-pg | teslamate | [[teslamate]] vehicle data |
| authentik | blumeops-pg | authentik | [[authentik]] identity provider |
| immich | immich-pg | immich | [[immich]] photo management |

The `immich-pg` cluster uses a custom image (`cloudnative-vectorchord`) with vector search extensions (vector, vchord, cube, earthdistance).

## Users

| User | Cluster | Role | Purpose |
|------|---------|------|---------|
| postgres | both | superuser | CNPG internal |
| miniflux | blumeops-pg | app owner | Owns miniflux database |
| teslamate | blumeops-pg | superuser | TeslaMate (needs extensions) |
| authentik | blumeops-pg | createdb | [[authentik]] identity provider |
| eblume | blumeops-pg | superuser | Admin access |
| borgmatic | both | pg_read_all_data | [[borgmatic|Backup]] access |
