Security: CVE-2016-0773

As pointed out by Michael Paquier, recovery_min_apply_delay didn't exist
in 9.0-9.3, making the release note text not very useful.  Instead make it
talk about recovery_target_xid, which did exist then.

9.0 is already out of support, but we can fix the text in the newer
branches' copies of its release notes.

Add entries for security and not-quite-security issues.

Security: CVE-2015-5288, CVE-2015-5289

Also sneak entries for commits 97ff2a564 et al into the sections for
the previous releases in the relevant branches.  Those fixes did go out
in the previous releases, but missed getting documented.

Revise description of CVE-2015-3166, in line with scaled-back patch.
Change release date.

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

Note: a few of these items actually don't apply to 9.3, but only to older
branches.  I'll sort that out when copying the text into the older
release-X.Y.sgml files.

I started out with the intention of just fixing the info about the jsonb
operator classes, but soon found myself copy-editing most of the JSON
material.  Hopefully it's more readable now.

Per gripe from Josh Berkus.

No substantive changes, but reorder some items and improve some
descriptions.

Make a bit more noise about the timeout-interrupt bug.  Also, remove the
release note entry for commit 423e1211; that patch fixed a problem
introduced post-9.3.2, so there's no need to document it in the release
notes.

We have a practice of providing a "bread crumb" trail between the minor
versions where the migration section actually tells you to do something.
Historically that was just plain text, eg, "see the release notes for
9.2.4"; but if you're using a browser or PDF reader, it's a lot nicer
if it's a live hyperlink.  So use "<xref>" instead.  Any argument against
doing this vanished with the recent decommissioning of plain-text release
notes.

Per suggestions from Andres Freund.  Also fix spelling of
Sergey Burladyan's name.

I'm putting these up for review before I start to extract the relevant
subsets for the older branches.  It'll be easier to make any suggested
wording improvements at this stage.

This is mostly to fix incorrect migration instructions: since the preceding
minor releases advised reindexing some GIST indexes, it's important that
we back-link to that advice rather than earlier instances.

Also improve some bug descriptions and fix a few typos.

No back-patch yet; these files will get copied into the back branches
later in the release process.

Some corrections, a lot of copy-editing.

Set projected release date as 2013-09-09.

Backpatch to 9.3.

Backpatch to 9.3.

Backpatch to 9.3, of course.

Move item about foreign data wrappers supporting inserts/updates/deletes
to object manipulation.
