Let me correct my own language:

What I mean is that "the exit status of the shell reflects the status of the
last command". That's why you'll see at the bottom of shscripts an "exit 0"
which might seem to be implied. Actually falling off the end of the script is
same as "exit" which is same as "exit $?" which may be nonzero if the preceding
command was a conditional/test, like:
for ...
if ...
fi
done
# without this, script will variously "fail" due to conditional evaluating to
# false:
exit 0
So I'm pointing out serious concern if psql would return 0 if last command
failed, a case where it's currently exiting with status 1.
