- Updated show_chunks, drop_chunks APIs to get the affected chunks using chunk creation time metadata based on the "date/time/interval" like boundary specified for the INTEGER columns. - We honor "integer_now" function if it's specified so as to keep backwards compatibility with the existing behavior Co-authored-by: Dipesh Pandit <dipesh@timescale.com>
