I don't know how to fix 82023d47^ on Windows[1][2], but in case it's
useful, here's a small clue. I see that Perl's readlink() does in
fact know how to read "junction points" on Windows[3], so if that was
the only problem it might have been very close to working. One
difference is that our own src/port/dirmod.c's pgreadlink() also
strips \??\ from the returned paths (something to do with the
various forms of NT path), but when I tried that:
my $olddir = readlink("$backup_path/pg_tblspc/$tsoid")
|| die "readlink
$backup_path/pg_tblspc/$tsoid: $!";
+ # strip NT path prefix (see src/port/dirmod.c
pgreadlink())
+ $olddir =~ s/^\\\?\?\\// if
$PostgreSQL::Test::Utils::windows_os;
... it still broke[4]. So I'm not sure what's going on...
