This patch is needed because the sql script is expecting the which
command to return errors on stderr, not stdout and assumes anything
on stdout is an actual path.   (And since /bin/which starts a new
csh, it only checks .cshrc $PATH not current $PATH settings.)

This patch will not be sent upstream.
