+      In the previous minor releases we added a patch to <function>fsync</>

+      response to any error condition was to fail, thereby preventing the
+      server from starting up, even when the problem was quite harmless.
+      An example is that an unwritable file in the data directory would
+      prevent restart on some platforms; but it is common to make SSL
+      certificate files unwritable by the server.  Revise this behavior so
+      that permissions failures are ignored altogether, and other types of
+      failures are logged but do not prevent continuing.
