The catalog table continuous_aggs_bucket_function is currently only used for variable bucket sizes. Information about the fixed-size buckets is stored in the table continuous_agg only. This causes some problems (e.g., we have redundant fields for the bucket_size, fixes size buckets with offsets are not supported, ...). This commit is the first in a row of commits that refactor the catalog for the CAgg time_bucket function. The goals are: * Remove the CAgg redundant attributes in the catalog * Create an entry in continuous_aggs_bucket_function for all CAggs that use time_bucket This first commit refactors the continuous_aggs_bucket_function table and prepares it for more generic use. Not all attributes are used yet, but these will change in follow-up PRs.
