Troubleshoot time buckets

Hierarchical continuous aggregate fails with incompatible bucket width

ERROR:  cannot create continuous aggregate with incompatible bucket width
DETAIL:  Time bucket width of "<BUCKET>" [1 year] should be multiple of the time bucket width of "<BUCKET>" [1 day].

If you attempt to create a hierarchical continuous aggregate, you must use compatible time buckets. You can't create a continuous aggregate with a fixed-width time bucket on top of a continuous aggregate with a variable-width time bucket. For more information, see the restrictions section in hierarchical continuous aggregates.
