(note: I've also posted this as a github issue https://github.com/timescale/timescaledb/issues/3653)
I have a hypertable request_logs configured with a 24 hour retention policy. The retention policy is being marked as running successfully, however no old data from the table is being removed. The table continues to grow day by day.
I checked and don't see any errors in the postgresql log files.
Could use additional guidance on where to look for information to troubleshoot this issue.
