Don't put <indexterm> before <term> in <varlistentry> items.

Doing that results in a broken index entry in PDF output.  We had only
a few like that, which is probably why nobody noticed before.
Standardize on putting the <term> first.

Avoid renaming data directory during MSVC upgrade testing.

This appears to cause some intermittent file system problems
on Windows 8. Instead, set up the old data directory in its
intended final location to start with.
Semi-automatically detect changes in timezone abbreviations.

Add an option to zic.c to dump out all non-obsolete timezone abbreviations
defined in the Olson database.  Comparing this list to its previous state
will clue us in when something happens that we may need to account for in
the tznames/ time zone abbreviation lists.  The README file's previous
exhortation to "just grep for differences" was completely useless advice,
in my now-considerable experience; but maybe this will be a bit more
useful.  As a starting point I built the same list from the tzdata files
as they existed in 2006, which is committed here as known_abbrevs.txt.
Comparison indeed turned up quite a few changes we had neglected to account
for, which I will commit separately.
Update time zone abbreviation lists for changes missed since 2006.

Most (all?) of Russia has moved to what's effectively year-round daylight
savings time, so that the "standard" zone names now mean an hour later
than they used to.  Update that, notably changing MSK as per recent
complaint from Sergey Konoplev, but also CHOT, GET, IRKT, KGT, KRAT,
MAGT, NOVT, OMST, VLAT, YAKT, YEKT.  The corresponding DST abbreviations
are presumably now obsolete, but I left them in place with their old
definitions, just to reduce any possible breakage from this change.

Also add VOLT (Europe/Volgograd), which for some reason we never had
before, as well as MIST (Antarctica/Macquarie), and fix obsolete
definitions of MAWT, TKT, and WST.
Add parallel pg_dump option.

New infrastructure is added which creates a set number of workers
(threads on Windows, forked processes on Unix). Jobs are then
handed out to these workers by the master process as needed.
pg_restore is adjusted to use this new infrastructure in place of the
old setup which created a new worker for each step on the fly. Parallel
dumps acquire a snapshot clone in order to stay consistent, if
available.

The parallel option is selected by the -j / --jobs command line
parameter of pg_dump.

Fix some unportable constructs in parallel pg_dump code.

Didn't compile on semi-obsolete gcc, and probably not on not-gcc-at-all
either.
Add missing #include.

time(2) requires time.h.
Add PF_PRINTF_ATTRIBUTE to on_exit_msg_fmt.

Per warning from -Wmissing-format-attribute.
Make pg_basebackup work with pre-9.3 servers, and add server version check.

A new 'starttli' field was added to the response of BASE_BACKUP command.
Make pg_basebackup tolerate the case that it's missing, so that it still
works with older servers.

Add an explicit check for the server version, so that you get a nicer error
message if you try to use it with a pre-9.1 server.

The streaming protocol message format changed in 9.3, so -X stream still won't
work with pre-9.3 servers. I added a version check to ReceiveXLogStream()
earlier, but write that slightly differently, so that in 9.4, it will still
work with a 9.3 server. (In 9.4, the error message needs to be adjusted to
"9.3 or above", though). Also, if the version check fails, don't retry.
In base backup, only include our own tablespace version directory.

If you have clusters of different versions pointing to the same tablespace
location, we would incorrectly include all the data belonging to the other
versions, too.

Fixes bug #7986, reported by Sergey Burladyan.
Fix a small logic bug in adjusted parallel restore code.
Get rid of obsolete parse_version helper function.

For getting the server's version in numeric form, use PQserverVersion().
It does the exact same parsing as dumputils.c's parse_version(), and has
been around in libpq for a long time. For the client's version, just use
the PG_VERSION_NUM constant.
Fix pg_dump against 9.1/9.2 servers.

The parallel pg_dump patch forgot to add relpages column to 9.1/9.2 version
of the getTables() query.

Reported by Bernd Helmle.
Ignore invalid indexes in pg_dump.

Dumping invalid indexes can cause problems at restore time, for example
if the reason the index creation failed was because it tried to enforce
a uniqueness condition not satisfied by the table's data.  Also, if the
index creation is in fact still in progress, it seems reasonable to
consider it to be an uncommitted DDL change, which pg_dump wouldn't be
expected to dump anyway.

Back-patch to all active versions, and teach them to ignore invalid
indexes in servers back to 8.2, where the concept was introduced.
