This should have been done in commit73c986addewhich added several new fields to pg_control, and again in commit5028f22f6ewhich changed the CRC algorithm, but it wasn't. It's far too late to fix it in the 9.5 branch, but let's do so in 9.6, so that if a 9.6 postmaster is started against a 9.4-era pg_control it will complain about a versioning problem rather than a CRC failure. We already forced initdb/pg_upgrade for beta3, so there's no downside to doing this now. Discussion: <7615.1468598094@sss.pgh.pa.us>
