Yep, and it's important for buildfarm logs to capture the verbose output.

The pg_upgrade test suite originated in an age when "make check-world" was
forbidden to depend on Perl; the choice was a shell script or a C program.  We
do maintain vcregress.pl:upgradecheck(), a Windows-specific Perl port of the
suite.  Maintaining both versions has been tedious.  I'd welcome a
high-quality rewrite using src/test/perl facilities.
