Postgres

Coming in the first release. This page describes behaviour being built for the first Gliss release. Details may change before it ships.

capabilities:
  database: { type: postgres, size: small, extensions: [vector] }

Live gets its own database cluster with backups. small is one instance; standard is two, for high availability.
Preview and Beta each get their own database on a shared Postgres of the same version.
The app receives the connection string as DATABASE_URL, and the usual PG* variables. Nobody types a database password.
Ask for extensions by their CREATE EXTENSION name. The platform creates them; your migrations must not.
Put the schema upgrade command in the component’s migrate field. It runs before each release, at every stage.
