Hello, Is there any way how to detect running command VACUUM by reading pg_* tables? The idea is to detectect when table is not accessible due maintainance. The approach of explicitely setting a flag into status table is not very convenient, while I want to cover also non-systematic launching of this command Regards, Bohdan ---------------------------(end of broadcast)--------------------------- TIP 3: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faq
