Pro tip: Copying a Postgres database while live transactions are interacting with it frequently results in a corrupt backup.

Thankfully I test my Luanti backups.

Edit: I should clarify - My dangerous backup method was a naive file copy. I’m sure there’s a different correct way to do a live backup. I just haven’t checked into it yet, since stopping my Luanti server for a backup is no big deal.

İirc they say dont do live backups as file copying but also docs say you could use filesystem snapshots

Yeah. I knew better, but it just didn’t occur to me until I was confirming my backups later.

Yikes! Thanks for the tip. I’m just starting to learn about Postgres. Think I’ll stick with MySQL or SQLite for now… :o

Choosing to not use something is not a good way to learn how to use it.

In this particular instance, the lesson is to either a) use the provided database tools (e.g. pg_dumpall) for live backup, or b) bring the database cluster down before you backup the raw data folder.
