The trick for that is to call COMMIT before you pass the backend to a
new person. Now, if you want to abort a left-over transaction, you can
do an ABORT but that is going to show up in the server logs because an
ABORT without a transaction causes an error message.
We also have RESET ALL for connection pooling use.
