About "Cost-based Vacuum Delay"

2018-06-15 Thread Ilyeop Yi
Hi Guys, I have some questions about "cost-based vacuum delay". Q1. How can I know/check if the autovacuum is actually paused periodically according to autovacuum_vacuum_cost_limit and autovacuum_vacuum_cost_delay? I cannot find such an information from log files. Q2. Is there
