I'm slightly confused. Most things I've read, including running
pg_tune for grins puts this around 100MB, 98MB for pgtune. 1-2MB just
seems really low to me. And Ignore the 300 connections, thats an upper
limit, I usually run a max of 40-45 but usually around 20 connections
per sec.
Also is there a way to log if there are any deadlocks happening (I'm
not seeing them in logs)
deadlock_timeout = 5s
