+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 regards, tom lane
