Tom Lane b163baa89c Clean up some problems with redundant cross-type arithmetic operators. Add ... int2-and-int8 implementations of the basic arithmetic operators +, -, *, /. This doesn't really add any new functionality, but it avoids "operator is not unique" failures that formerly occurred in these cases because the parser couldn't decide whether to promote the int2 to int4 or int8. We could alternatively have removed the existing cross-type operators, but experimentation shows that the cost of an additional type coercion expression node is noticeable compared to such cheap operators; so let's not give up any performance here. On the other hand, I removed the int2-and-int4 modulo (%) operators since they didn't seem as important from a performance standpoint. Per a complaint last January from ykhuang.		2008-06-17 19:10:56 +00:00
