Hi, I have PostgreSQL v9.4.4 running in my environment. It has been up for over 2 years now. I noticed that suddenly the statistics have been reset and all the stat tables/columns got restarted from.
This happened 2 weeks ago. I noticed only recently after I looked at the plot over last week (which dipped suddenly for "number of tuples returned", "number of conflicts" etc). The columns which got reset are from pg_stat_database, pg_stat_user_tables, pg_stat_bgwriter As far I know no one has fired pg_stat_reset or pg_stat_reset_shared. I noticed that the last largest value is from pg_stat_user_tables. tup_returned (470440261405). Does the statistics get reset automatically when the value for one of the statistics reaches the high number supported by int4? I am running on Red Hat 6.7.
