    Hi all
    As I understand every time there is a request to postgres a new backend is made, and when the request is finished, even if the connection is already active the backend dies. I wonder if is there any parameter that allow backends to remain beyond a transaction. Creating a new backend every time a transaction is made means forking the code and reallocating sort_memory. Although it is not a high resource usage, on short transactions as OLTPs it is a relevant work time, I think it would be interesting that a predefined number of backends were allowed to remain active beyond the transaction.
    Thanks and Regards
