Lock relation used to generate fresh data for RMV. Back-patch the 9.4-era commit 2636ecf78 into 9.3, as that fixes a case where we open a relation while not holding any lock on it. It's probably mostly safe anyway, since no other session could touch the newly-created table; but I think CheckTableNotInUse could be fooled if one tried.
Per testing with a patch that complains if we open a relation without holding any lock on it. I don't plan to back-patch that patch, but we should close the holes it identifies in all supported branches.
