Thread: pgsql: Replace use of "diff -q".

Replace use of "diff -q".

POSIX does not specify the -q option, and many implementations do not
offer it.  Don't bother changing the MSVC build system, because having
non-GNU diff on Windows is vanishingly unlikely.  Back-patch to 9.2,
where this invocation was introduced.
