I've got a "problem" with stats at PostgreSQL 9.3. Problem can coupe(?) sources: a) I do not understand what values should tup_returned contain b) tup_returned contains something else than can be understood by reading official docs c) something is wrong with our database "server"
What's my problem? This (test) database isn't used by any user/script, password was set randomly and I don't even know it. Database is left untouched, tup_returned climbs quite high at rate ~ 65k per hour. btw. there's only one table with 2 rows inside. Same thing happens for all 9.3 instances in all databases configured in our environment.
I'd be very glad if someone could explain to me what should I expect from tup_returned or how can I meter "rows returned from database".
