Not share/ surely, since these are executables, but yeah.
This brings me to the idea that "pg" is a very small stupid program
that just tries to match its first argument against a filename in
PREFIX/libexec/postgresql. If it finds a match it execs that program
with the remaining args, else it fails. If we do it that way then the
problem of a client-only installation is solved: it merely has a smaller
population of files in PREFIX/libexec, and "pg" doesn't know the
difference. Also the problem of optionally providing the old names just
reduces to providing links in bin/, whereas with a melded executable
we'd need still more smarts to look at how it'd been invoked.
So +2 or so for this one.
