Обсуждение: timeout for "idle in transaction"
Is there a way to automatically ROLLBACK transactions that are in "idle in transaction" for too long ? I remember it has been discussed on this list, but what is the current status ? This is a problem that has haunted me on several web applicatons using application servers that have persistent connection (Zope, apache-php with persistent connections) ------------------- Hannu

This can't be done from the client side and we do have other types of deadlock detection on server side so this seems to quite appropriate from where I stand. I guess it would be quite nice to have as a connection-level setting, so that things that benefit from it can set it to some reasonable value while others that want to behave unsocially can do it as well ;) The default could be 1-3 sec of idle time in transaction for typical client-server and web apps while command line clients (like psql) could set it to something more automatically. ----------------- Hannu
