pg_stat_progress_vacuum.delay_time
Total time spent sleeping due to cost-based delay (see Section 19.10.2), in milliseconds (if track_cost_delay_timing is enabled, otherwise zero). This includes the time that any associated parallel workers have slept. However, parallel workers report their sleep time no more frequently than once per second, so the reported value may be slightly stale.
