Draft release notes for next week's back-branch releases - Mailing list pgsql-hackers

I've put up draft notes for 9.5.4 at

https://git.postgresql.org/gitweb/?p=postgresql.git;a=commitdiff;h=3676631c687009c2fadcb35e7d312e9eb8a98182

The website should have them after guaibasaurus's next run, due a couple
hours from now.

As usual, the older branches will have subsets of these notes (but there
is one item about pg_ctl that applies only to 9.1).  Please review in the
next 24 hours.
        regards, tom lane
