[devtools] improve error message when postgresql tools are missing
By default in at least Debian, some pg tools are not present in the
PATH. Or they may not be installed. But the tests tools expects them
to be in the PATH, and give an unhelpful 'No such file or directory'
backtrace if they're not found. To help devs using the pg tests we
improve the error message.
