MSYS2 and pg_upgrade testing

I've been getting an Msys2 environment working, and will soon document
how to build with this environment. There are several nice things
about it, including a modern version of perl and proper support for
the mingw-w64 compilers.

So far the only thing I have found that needs to be changed for us to
support it is this, which is so trivial and low risk that I propose to
backpatch it to all live releases:

diff --git a/src/bin/pg_upgrade/test.sh b/src/bin/pg_upgrade/test.sh
index a805018..45ccd8f 100644
--- a/src/bin/pg_upgrade/test.sh
+++ b/src/bin/pg_upgrade/test.sh
@@ -34,7 +34,7 @@ standard_initdb() {
 testhost=`uname -s`

 case $testhost in
-   MINGW*)
+   MINGW*|MSYS*)
        LISTEN_ADDRESSES="localhost"
        PGHOST=localhost
        ;;


cheers
