Is rdstopmgr an AWS RDS user?



  • I am running postgres on AWS RDS. RDS creates some users on its own, such as rdsadmin and rdsrepladmin. I am familiar with these

    However, I also see rdstopmgr, when I query postgres for roles. Google doesn't have much to say about this user, and neither does https://docs.aws.amazon.com/en_us/search/doc-search.html?searchPath=documentation&searchQuery=rdstopmgr . However, I think this may be an RDS user as well.

    Here's why: When I Google 'RDS top', I find https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_PerfInsights.UsingDashboard.Components.AvgActiveSessions.TopLoadItemsTable.TopSQL.html from AWS RDS docs. This makes me think rdstopmgr may be an RDS controlled user that is used for performance insights.

    I've submitted a feedback to AWS requesting they update their docs to include this. However I also wanted to pose this to the community here. Do you agree with my conclusion, or do you know otherwise about this user?



  • Taken from https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/Appendix.PostgreSQL.CommonDBATasks.html :

    rdstopmgr – A role that's used internally by Amazon RDS to support Multi-AZ deployments.
