Cheers to @MattHill for being more specific than K3tan.
Sad to hear about their issues with Raspberry Pi power management on shoddy grids/wires. Probably quite very edge case but with enough customers it becomes an issue.
ElectRS might need some tuning to be kinder to the Pi's. At least it's written in Rust and not Python/JS.
I still think being able to run as an uncle Jim using a Pi is drawing an important line in the sand. A PC is too elastic a definition, allowing too much bloat/cost to accumulate at a more rapid pace.
Using Postgres to store service versions etc seems a bit overkill. Maybe it was the power issues making SQLite malfunction, or possibly there’s some flushing to disk command that could be used. Please excuse the speculation. Have the impression the SQLite is some of the most robust software out there.
