- Added creation_time attribute to timescaledb catalog table "chunk". Also, updated corresponding view timescaledb_information.chunks to include chunk_creation_time attribute. - A newly created chunk is assigned the creation time during chunk creation to handle new partition range for give dimension (Time/ SERIAL/BIGSERIAL/INT/...). - In case of an already existing chunk, the creation time is updated as part of running upgrade script. The current timestamp (now()) at the time of upgrade has been assigned as chunk creation time. - Similarly, downgrade script is updated to drop the attribute creation_time from catalog table "chunk". - All relevant queries/views/test output have been updated accordingly.
