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. 1999-07-19 02:26:20 +02:00			`* $Id: parse_node.h,v 1.15 1999/07/19 00:26:17 tgl Exp $`

Remove Query->qry_aggs and qry_numaggs and replace with Query->hasAggs. Pass List* of Aggregs into executor, and create needed array there.
