+- Images are tagged by the major PostgreSQL version supported: `12`, `13`, `14`, `15`, `16` or `17`.
 - The `SCHEDULE` variable determines backup frequency. See go-cron schedules documentation [here](http://godoc.org/github.com/robfig/cron#hdr-Predefined_schedules). Omit to run the backup immediately and then exit.
 - If `PASSPHRASE` is provided, the backup will be encrypted using GPG.
 - Run `docker exec <container name> sh backup.sh` to trigger a backup ad-hoc.
