Thread: Database Stats getting reset after server restart
Hi Team,
After the postgresql server restart, the details on the pg_stat_all_tables are showing as zero. Does that mean the stats data also gets reset after the server restart ? How can we prevent this from happening?
Regards,
Sujith Kumar.S

Yes, it's a force restart of the server. Is there any option to avoid the stats data loss after an unexpected shutdown and recovery process.

Hi Sujith
Did you set the vacuum parameter on this table automatically?
Thanks & Best Wishes,
