Thanks for ur reply Ragu.. Yes, I have executed this select pg_stat_reset(); as a root user. It has reseted the values. But last time ( when I was posted this query) I didn't executed it. But values were rested automatically. I would like to know, => Whether postgres automatically running this select pg_stat_reset(); statement ? => If it runs Which scenario its executing this statement and what is the interval time between each execution ? Please let me know..
