Thanks, and that was indeed one reason I wanted dropdb --if-exists. > I also just made the exit code 1 > no matter how many failures there were.

The old book "The Unix Programming Environment" (section "Arithmetic in sh") claims that using expr or bc is the only way to do such arithmetic, e.g.: var=`expr $var + 1` But then  documents arithmetic expansion as used in the patch. But anyway, just returning 1 as you've done seems fine.
