### Step 1: Ensure postgresql minimum requirements are met

MinIO requires PostgreSQL version 9.5 or above. MinIO uses the [`INSERT ON CONFLICT`](https://www.postgresql.org/docs/9.5/static/sql-insert.html#SQL-ON-CONFLICT) (aka UPSERT) feature, introduced in version 9.5 and the [JSONB](https://www.postgresql.org/docs/9.4/static/datatype-json.html) data-type introduced in version 9.4.

### Step 2: Add PostgreSQL endpoint to MinIO
