Seems redundant.
SHELL_ERROR is helpful in that it is a ready-made boolean that works for \if tests in the same way that ERROR is set to true any time SQLSTATE is nonzero. We don't yet have inline expressions for \if so the ready-made boolean is a convenience.
Or are you suggesting that I should have just set ERROR itself rather than create SHELL_ERROR?
