Just for the archives' sake: I dug through the OS X source code archives
and confirmed that this behavior changed at 10.3: compare getproclline
in 10.2.8

vs 10.3

So we don't need a version check unless you're worried about somebody
trying to run Postgres 9.x on OS X 10.2 (which was retired in 2003).
