This commit adds the amount of time spent sleeping due to cost-based delay to the pg_stat_progress_vacuum and pg_stat_progress_analyze system views. A new configuration parameter named track_cost_delay_timing, which is off by default, controls whether this information is gathered. For vacuum, the reported value includes the sleep time of any associated parallel workers. However, parallel workers only report their sleep time once per second to avoid overloading the leader process. Bumps catversion.
