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.
