As usual, the release notes for older branches will be made by cutting
these down, but put them up for community review first.

+      Disallow SSL renegotiation more completely (Michael Paquier)
+     </para>
+
+     <para>
+      SSL renegotiation has been disabled for some time, but the server
+      would still cooperate with a client-initiated renegotiation request.
+      A maliciously crafted renegotiation request could result in a server
+      crash (see OpenSSL issue CVE-2021-3449).  Disable the feature
+      altogether on OpenSSL versions that permit doing so, which are
+      1.1.0h and newer.

+      Avoid misbehavior when persisting the output of a cursor that's
+      reading a non-stable query (Tom Lane)
+     </para>
+
+     <para>
+      Previously, we'd always rewind and re-read the whole query result,
+      possibly getting results different from the earlier execution,
+      causing great confusion later.  For a NO SCROLL cursor, we can fix
+      this by only storing the not-yet-read portion of the query output,
+      which is sufficient since a NO SCROLL cursor can't be backed up.
+      Cursors with the SCROLL option remain at hazard, but that was
+      already documented to be an unsafe option to use with a non-stable
+      query.  Make those documentation warnings stronger.
+     </para>
+
+     <para>
+      Also force NO SCROLL mode for the implicit cursor used by
+      a <application>PL/pgSQL</application> FOR-over-query loop,
+      to avoid this type of problem when persisting such a cursor
+      during an intra-procedure commit.

+      Prevent infinite loops in SP-GiST index insertion (Tom Lane)

+
+     <para>
+      In the event that INCLUDE columns take up enough space to prevent a
+      leaf index tuple from ever fitting on a page, the text_ops operator
+      class would get into an infinite loop vainly trying to make the
+      tuple fit.
+      While pre-v11 versions don't have INCLUDE columns, back-patch this
+      anti-looping fix to them anyway, as it seems like a good defense
+      against bugs in operator classes.

+     <para>
+      Allow isolation test steps to be annotated to show the expected
+      completion order.  This allows getting stable results from
+      otherwise-racy test cases, without the long delays that we
+      previously used (not entirely successfully) to fend off race
+      conditions.
+      Allow non-quoted identifiers as isolation test session/step names
+      (formerly, all such names had to be double-quoted).
+      Detect and warn about unused steps in isolation tests.
+      Improve display of query results in isolation tests.
+      Remove isolationtester's <quote>dry-run</quote> mode.
+      Remove memory leaks in isolationtester itself.

+
+     <para>
+      The GSSAPI spec provides for a string pointer and length.  It seems
+      that in practice the next byte after the string is usually zero,
+      so that our previous coding didn't actually fail; but we do have
+      a report of AddressSanitizer complaints.
