Tasks of After Major Version Upgrade

  • Run the ANALYZE operation to refresh the pg_statistic table.
  • Optionally, use Amazon RDS to view two logs that the pg_upgrade utility produces. These are pg_upgrade_internal.log and pg_upgrade_server.log. Amazon RDS appends a timestamp to the file name for these logs. You can view these logs as you can any other log. For more information, see Amazon RDS database log files.You can also upload the upgrade logs to Amazon CloudWatch Logs. For more information, see Publishing PostgreSQL logs to CloudWatch Logs.
  • To verify that everything works as expected, test your application on the upgraded database with a similar workload. After the upgrade is verified, you can delete this test instance.
