Hello,
I have observed that after upgrading from 9.3 to 9.4 on windows, autovacuum keep running again and again.
In 9.3 this was not true. Any recommendations?
Thanks & Regards,

These are all shared catalogs. There are others, so you may still see more. We got another report for pg_database https://www.postgresql.org/message-id/A9D40BB7-CFD6-46AF-A0A1-249F04878A2A%40amazon.com
so I suppose there really is a bug. I don't know what's going on there.
