 policies from failing. For example, consider a refresh policy like this:
 
 ```sql
-SELECT add_continuous_aggregate_policy('cagg_name', start_offset=>'30 days', end_offset=>'1 day', '1 h');
+SELECT add_continuous_aggregate_policy('cagg_name',

 With this kind of refresh policy, the compression policy needs the `compress_after`
