Use the logging collector with its built-in rotation parameters, and you
don't need anything else.

If you insist on an external solution, there's basically no way except
to shut down and restart postgres after any rotation, because there are
going to be N processes all connected to the same stderr file descriptor.

Well, that depends on what you want to do.  I like to choose the log file
names so that they'll automatically be reused once a week or month.
