extern Expr *make_op(char *opname, Node *ltree, Node *rtree);
Remove bogus code in oper_exact --- if it didn't find an exact match then it tried for a self-commutative operator with the reversed input data types. This is pretty silly; there could never be such an operator, except maybe in binary-compatible-type scenarios, and we have oper_inexact for that. Besides which, the oprsanity regress test would complain about such an operator. Remove nonfunctional code and simplify routine calling convention accordingly.

char *attrname);
Rewrite parser's handling of INSERT ... SELECT so that processing of the SELECT part of the statement is just like a plain SELECT. All INSERT-specific processing happens after the SELECT parsing is done. This eliminates many problems, e.g. INSERT ... SELECT ... GROUP BY using the wrong column labels. Ensure that DEFAULT clauses are coerced to the target column type, whether or not stored clause produces the right type. Substantial cleanup of parser's array support.
