+1 for adding the extra details, but another thing that I've always found
very confusing is just the phrasing of the message itself. It makes
no sense unless (a) you know that "system" is Perl's function for
executing a shell command, (b) you are familiar with Perl's generally
cavalier approach to parentheses, and (c) you are also unbothered by
whether the word "failed" is part of the message text or the command
being complained of. We really need to do something to set off the
shell command's text from the surrounding verbiage a little better.
I'd prefer something like
command "pg_ctl start" failed: details here
