Additional Information

Old metric data can be deleted with the following SQL

delete from metric where extract(hour from timestamp) != 21;

deletes all entries which are not made in 21st hour - only keeps one measurement per day taken during 21:00-21:59

This seems like a great quick fix. We may want to revisit how we track metrics in the future (e.g. same db vs different db, timescale vs normal table, etc), but we can refer back to #95 to continue that discussion.
