First cut at full support for OUTER JOINs. There are still a few loose ends to clean up (see my message of same date to pghackers), but mostly it works. INITDB REQUIRED!

* State information used during parse analysis
Carry column aliases from the parser frontend. Enables queries like SELECT a FROM t1 tx (a); Allow join syntax, including queries like SELECT * FROM t1 NATURAL JOIN t2; Update RTE structure to hold column aliases in an Attr structure.

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.

extern Var *make_var(ParseState *pstate, RangeTblEntry *rte, int attrno);
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.
