At constraint definition time, I need to make sure that the strategy numbers can be identified anyway, so it wouldn't save any work in ATAddOperatorExclusionConstraint. At the time it seemed slightly more direct to use strategy numbers in index_check_constraint, but it's probably about the same. > It seems like this could lead to surprising behavior if > the user modifies the definition of the operator class. Right now, operator classes can't be modified in any meaningful way.

Are you suggesting I change the error output, or reorganize the code to try to reuse BuildIndexValueDescription, or both?
