Hi Tom-san.
I look at that all regression tests pass by tools/msvc. It is very comfortable.!
Then, the reason, it is because no-locale is an default value.
-- my @args = ( "../../../$Config/pg_regress/pg_regress", "--psqldir=../../../$Config/psql",
"--schedule=${schedule}_schedule", "--multibyte=SQL_ASCII", "--load-language=plpgsql", "--no-locale"
--
It is why here. -- Is it no-locale?
