+ Avoid failures while <function>fsync</>'ing data directory during
+ crash restart (Abhijit Menon-Sen, Tom Lane)
+ </para>
+
+ <para>
+ In the previous minor releases we added a patch to <function>fsync</>
+ everything in the data directory after a crash. Unfortunately its
+ 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.

+ protocol it would allow was TLS v1. Now that newer TLS versions are
+ becoming popular, allow it to negotiate the highest commonly-supported
+ TLS version with the server. (<productname>PostgreSQL</> servers were
+ already capable of such negotiation, so no change is needed on the
+ server side.) This is a back-patch of a change already released in
+ 9.4.0.
