  PaaS->>Dev: DATABASE_URL injected
  PaaS->>Dev: addon ready

Create an add-on

paas addons create database --type postgres --plan standard --name db

PaaS injects connection details as environment variables into your app:

Variable	Value
DATABASE_URL	postgres://user:pass@host:5432/dbname
DATABASE_HOST	pg-inst-1.addons.svc
DATABASE_PORT	5432

A new deploy is triggered automatically with these vars present.

PITR backups

PostgreSQL add-ons get automated PITR (Point-In-Time Recovery) backups to S3-compatible storage:

Plan	Retention	RPO
free	none	n/a
starter	7 days	1h
standard	30 days	5min
pro	90 days	1min

Restore to a point in time:

paas addons:restore db --to "2026-05-04T10:30:00Z"

Read replicas

For standard and pro plans:

paas addons:replicas db --count 2 --region eu-fr-2

DATABASE_REPLICA_URL is injected for read traffic.
