-        By default, if non-interactive scripts encounter an error, such

-        is sometimes not desirable. If this variable is set, script
-        processing will immediately terminate. If the script was called
-        from another script it will terminate in the same fashion. If
-        the outermost script was not called from an interactive
-        <application>psql</application> session but rather using the
-        <option>-f</option> option, <application>psql</application> will

-        conditions (error code 1).

+        any currently running scripts (the toplevel script, if any, and any
+        other scripts which it may have in invoked) will be terminated

+        commands, processing will stop with the current command.
