### Choose the right version
We publish multiple builds targeting specific PostgreSQL versions (now its 15, 16, and 17). While you can always use the latest version, it's recommended to choose the build that matches your server's PostgreSQL version. This prevents compatibility issues where you might create a backup that can't be restored on your current server. For example, if you're running PostgreSQL 15, use tag `1.3.0-pg15` instead of `1.3.0` or `latest`.

For PostgreSQL 15 or older, pick an earlier release — see [releases](https://github.com/f213/postgres-backup-s3/releases).
