Could those be new backends that have been forked off the main
postmaster, but haven't yet gotten around to changing their ps info?
I'm not sure what would block a new backend for many minutes before
it did that, however. Can you attach to one of these processes with
a debugger and get a backtrace to show what it's doing?
