I'm looking for an efficient method to back up and restore my PostgreSQL database hosted on Railway. Ideally, I want to create backups in .csv format for easier readability and integration with other tools. The goal is to use just a connection string to handle both the backup and restoration processes. I've attempted to write custom JavaScript scripts for this, but face challenges with things like relationships, markdown strings, and restoration order. While I know tools like PgAdmin and pg_dump exist, they don't support automatic CSV uploads to S3 for backups. Does anyone have a simple and effective workflow for duplicating the entire PostgreSQL data that's also free and open-source? Or am I approaching this the wrong way?

Using pg_dump is probably your best bet since it's reliable and widely used. From what I've seen at work, we created our own scripts that integrate pg_dump with S3 for backups. Basically, you'd set up a server to run pg_dump, convert the output into .csv files, and regularly upload those to S3 using a cron job. Then when you need to restore, you can download the backups from S3 and use your script to reinstate your data. It might be a bit of setup initially, but it works well in the long run.
