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.

The PostgreSQL contrib tree
---------------------------
This subtree contains porting tools, analysis utilities, and plug-in
features that are not part of the core PostgreSQL system, mainly
because they address a limited audience or are too experimental to be
part of the main source tree. This does not preclude their
usefulness.
User documentation for each module appears in the main SGML
documentation.
When building from the source distribution, these modules are not
built automatically, unless you build the "world" target. You can
also build and install them all by running "gmake all" and "gmake
install" in this directory; or to build and install just one selected
module, do the same in that module's subdirectory.
Some directories supply new user-defined functions, operators, or
types. To make use of one of these modules, after you have installed
the code you need to register the new SQL objects in the database
system by executing a CREATE EXTENSION command. In a fresh database,
you can simply do
CREATE EXTENSION module_name;
See the PostgreSQL documentation for more information about this
procedure.
