I also found that 010_dump_connstr fails, if Windows has UTF-8 option on
(in language setting,
mentioned as beta feature in option description).

It looks like this test does not consider language settings. It creates
user with a long name,
language settings can increase this name by 2 times in UTF-8 case,
Postgres cut this name to 64 bytes, but the test continues to use
original long name and fails.
It is not clear, what exactly the test checks, if it fails before the
dump check.
