Tom Lane 31d1f23302 Teach simplify_boolean_equality to simplify the forms foo <> true and ... foo <> false, along with its previous duties of simplifying foo = true and foo = false. (All of these are equivalent to just foo or NOT foo as the case may be.) It's not clear how often this is really useful; but it costs almost nothing to do, and it seems some people think we should be smart about such cases. Per recent bug report.		16 years ago
