The database of your app
On the App plan your app gets its own Postgres database and its own user on a server that is used only for App customers, in the EU (Ireland). The connection string is in DATABASE_URL. Limits: 1 GB and 10 connections per app. Use a connection pool in your app; ten connections is enough for a normal Node app but not for one that opens a connection per request.
Backups: point-in-time restore of the last 7 days on the server; ask in a ticket if you need a restore. Deleting the app keeps the database 30 days as a backup, then it is dropped.
Your own server: on the usage-based plan you can switch on a dedicated Postgres server (B1ms to B4ms) at the rate on /rates; a stopped server is kept 7 days, then deleted.
Export: ask in a ticket for a pg_dump of your database; we provide it as a file.
