+

+      Any local user able to access the socket file could connect as the

+      the operating-system user running the test, as we previously noted in
+      CVE-2014-0067.  This change defends against that risk by placing the
+      server's socket in a temporary, mode 0700 subdirectory
+      of <filename>/tmp</>.  The hazard remains however on platforms where
+      Unix sockets are not supported, notably Windows, because then the
+      temporary postmaster must accept local TCP connections.

+
+     <para>
+      A useful side effect of this change is to simplify

+      like <filename>/var/run/postgresql</> are often not writable by the

+      Any local user able to access the socket file could connect as the

+      the operating-system user running the test, as we previously noted in
+      CVE-2014-0067.  This change defends against that risk by placing the
+      server's socket in a temporary, mode 0700 subdirectory
+      of <filename>/tmp</>.  The hazard remains however on platforms where
+      Unix sockets are not supported, notably Windows, because then the

+      This change reduces the amount of indentation applied to nested
+      constructs, including some cases that the user probably doesn't think
+      of as nested, such as UNION lists.  Previously, deeply nested
+      constructs were printed with an amount of whitespace growing as
+      O(N^2), which created a performance problem and even risk of
+      out-of-memory failures.  Now the indentation is reduced modulo 40,
+      which is initially odd to look at but seems to preserve readability
+      better than simply limiting the indentation would do.
+      Redundant parenthesization of UNION lists has been reduced as well.

+      Secure Unix-domain sockets of temporary postmasters started during

+     </para>
+
+     <para>
+      Any local user able to access the socket file could connect as the
+      server's bootstrap superuser, then proceed to execute arbitrary code as
+      the operating-system user running the test, as we previously noted in
+      CVE-2014-0067.  This change defends against that risk by placing the
+      server's socket in a temporary, mode 0700 subdirectory
+      of <filename>/tmp</>.  The hazard remains however on platforms where
+      Unix sockets are not supported, notably Windows, because then the
+      temporary postmaster must accept local TCP connections.
+     </para>
+
+     <para>
+      A useful side effect of this change is to simplify
+      <literal>make check</> testing in builds that
+      override <literal>DEFAULT_PGSOCKET_DIR</>.  Popular non-default values
+      like <filename>/var/run/postgresql</> are often not writable by the
+      build user, requiring workarounds that will no longer be necessary.
