PostgreSQL DEV plan moves to PostgreSQL 18

The shared clusters behind the free DEV plan of PostgreSQL now run PostgreSQL 18, the default version of dedicated add-ons since 15 September. A new DEV add-on runs PostgreSQL 18.6, so you can test your application against the same major version you use in production:

The DEV plan remains for testing purposes only: it comes without backups, extensions or SLA. For production workloads, use a dedicated plan.
