timescaledb/tsl/test/sql/remote_copy.sql
Dipesh Pandit 0b87a069e7 Add metadata for chunk creation time 
- 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.
