How else would it work?

If I say, syntax aside, listen on "ports" 5432 and 5433, and use socket
directories /tmp and /var/run/postgresql, then a libpq-using client
would expect to be able to connect using

-h /tmp -p 5432
-h /tmp -p 5433
-h /var/run/postgresql -p 5432
-h /var/run/postgresql -p 5433

So you do need to create M*N sockets.

I don't really see a problem with that.
