The only way that I'm aware of for disabling this is at compile time ... after running configure, you want to modify:

src/include/pg_config.h

and undef HAVE_SETPROCTITLE ...

I'm CC'ng -hackers about this though, since I think you are the first to point to setproctitle() as being a serious performance bottleneck ...
