When commit 0f33a719fdbb5d8c43839ea0d2c90cd03e2af2d2 removed the
instructions to start/stop the new cluster before running rsync, it was
now possible for pg_resetwal/pg_resetxlog to leave the final WAL record
at wal_level=minimum, preventing upgraded standby servers from
reconnecting.
This patch fixes that by having pg_upgrade unconditionally start/stop
the new cluster after pg_resetwal/pg_resetxlog has run.
Backpatch through 9.2 since, though the instructions were added in PG
9.5, they worked all the way back to 9.2.

Backpatch-through: 9.2
This patch causes pg_upgrade to error out during its check phase if:
(1) template0 is marked connectable
or
(2) any other database is marked non-connectable
This is done because, in the first case, pg_upgrade would fail because
the pg_dumpall --globals restore would fail, and in the second case, the
database would not be restored, leading to data loss.

Backpatch through 9.0
If the locale names are not equal, try to canonicalize both of them by
passing them to setlocale(). Before, we only canonicalized the old cluster's
locale if upgrading from a 8.4-9.2 server, but we also need to canonicalize
when upgrading from a pre-8.4 server. That was an oversight in the code. But
we should also canonicalize on newer server versions, so that we cope if the
canonical form changes from one release to another. I'm about to do just
that to fix bug #11431, by mapping a locale name that contains non-ASCII
characters to a pure-ASCII alias of the same locale.
This is partial backpatch of commit 33755e8edf149dabfc0ed9b697a84f70b0cca0de
in master. Apply to 9.2, 9.3 and 9.4. The canonicalization code didn't exist
before 9.2. In 9.2 and 9.3, this effectively also back-patches the changes
from commit 58274728fb8e087049df67c0eee903d9743fdeda, to be more lax about
the spelling of the encoding in the locale names.
Some popen() calls were missing SYSTEMQUOTEs, which caused initdb and
pg_upgrade to fail on Windows, if the installation path contained both
spaces and @ signs.
Patch by Nikhil Deshpande. Backpatch to all supported versions.
Thinko in error report (and a typo in the message text, too). We're
failing anyway, but it would be good to print something useful first.
Noted while reviewing a patch to make pg_upgrade's locale code laxer.
Now that pg_dump no longer dumps invalid indexes, per commit
683abc73dff549e94555d4020dae8d02f32ed78b, have pg_upgrade also skip
them. Previously pg_upgrade threw an error if invalid indexes existed.
Backpatch to 9.2, 9.1, and 9.0 (where pg_upgrade was added to git)
All versions of pg_upgrade upgraded invalid indexes caused by CREATE
INDEX CONCURRENTLY failures and marked them as valid. The patch adds a
check to all pg_upgrade versions and throws an error during upgrade or
--check.
Backpatch to 9.2, 9.1, 9.0. Patch slightly adjusted.
socket location. Also, prevent putting the socket in the current
directory for pre-9.1 servers in live check and non-live check mode,
because pre-9.1 pg_ctl -w can't handle it.
Backpatch to 9.2.
pg_upgrade produces a platform-specific script to remove the old
directory, but on Windows it has not been making sure that the
paths it writes as arguments for rmdir and del use the backslash
path separator, which will cause these scripts to fail.
The fix is backpatched to Release 9.0.
This syncs contrib/pg_upgrade in the 9.2 branch with HEAD, except for the
HEAD changes related to converting XLogRecPtr to 64-bit int. It includes
back-patching these commits:

There's no reason for this test to use the undocumented pg_prepared_xact()

Fixes breakage against 8.3, as reported by Justin Arnold.
Add errno-based output to error messages where appropriate, reformat
blocks to about 72 characters per line, use spaces instead of tabs for
indentation, and other style adjustments.
