I'm late to the party on this which is my fault, I had my head down on
other stuff. But I just noticed this commit. Unfortunately the commit
message and this thread contain suggestions that aren't true. How do I
know? Because the buildfarm has for years called pg_ctl via cmd.exe with
a relative path with forward slashes. here's the relevant perl code that
runs on all platforms:
chdir($installdir);
my $cmd =
qq{"bin/pg_ctl" -D data-$locale -l logfile -w start >startlog
2>&1};
system($cmd);
Note that the pg_ctl path is quoted, and those quotes are passed through
to cmd.exe. That's what makes it work. It's possibly not worth changing
it now, but if anything that's the change that should have been made here.
Just wanted that on the record in case people got this wrong idea that
you can't use forward slashes when calling a program in cmd.exe.
