When time_bucket is compared to constant in WHERE, we also add condition on the underlying time variable (ts_transform_time_bucket_comparison). Unfortunately we only do this for plan-time constants, which prevents chunk exclusion when the interval is given by a query parameter, and a generic plan is used. This commit also tries to apply this optimization after applying the execution-time constants. This PR also enables startup exclusion based on parameterized filters.
