It is not because of the locks. There is only running transaction (and it
got every locks). Not sure why the backend stucks there, seems it doesn't
aware of the broken client. In normal situations, if you killed a client,
then the server will print something like "could not receive data from
client" then exit the backend.
If you can attach to the problematic postgres process, that would be more
helpful to identify the problem.
