    ARM notes for PostgreSQL

    The official Postgres image is multi-arch, so it runs natively on Ampere. The Always Free block volume allowance (200 GB total) is far more storage than most free managed database tiers offer.

    Skip the build, network and TLS setup

    Cheaploy builds this image on your own Oracle Always Free VM, opens the ports, issues HTTPS and rolls back if health checks fail.
