That seems like a pretty big deal.

Does a WAL backup approach work?

[akulkarni]

TimescaleDB offers a number of backup and restore options, including wal-e (WAL-based), pg_dump & pg_restore:

There are hundreds of thousands of TimescaleDB databases in production so this is generally not an issue.

Seemed like an odd issue to be outstanding. I assume if this was a real issue it would be a much bigger story.

Correct, the issue is due to confusing notices printed during pg_dump as it uses COPY TO underneath.
