Desultory review of 9.5 release notes. 

Minor corrections and clarifications.  Notably, for stuff that got moved
out of contrib, make sure it's documented somewhere other than "Additional
Modules".

I'm sure these need more work, but that's all I have time for today.

enabled to warn about queries where the precedence has changed. (e.g., <replaceable>x</> <literal>IS NULL</>) has been reduced to be
just below these six comparison operators.
Also, multi-keyword operators beginning with <literal>NOT</> now have
the precedence of their base operator (for example, <literal>NOT
BETWEEN</> now has the same precedence as <literal>BETWEEN</>) whereas
before they had inconsistent precedence, behaving like <literal>NOT</>
with respect to their left operand but like their base operator with
respect to their right operand. The new configuration
parameter <xref linkend="guc-operator-precedence-warning"> can be

than before; for example, assigning a numeric value <literal>3.9</> to
an integer variable will now assign 4 rather than failing. If no
assignment-grade cast is defined for the particular source and
destination types, <application>PL/pgSQL</> will fall back to its old
