Oh ... 2005 was just the last time anybody touched that particular
line in backend/Makefile. Further digging shows that we've been
installing the postmaster -> postgres symlink with raw "ln -s"
clear back to the Postgres95 virgin sources. I didn't bother to
chase down the oldest instances of the other two cases.

(Man, "git blame" is such a great tool for software archaeology.)
