ITYM transformStmt, but yeah, somewhere around there is probably reasonable.
The way I'm imagining this would work is that IntoClause disappears from
Query altogether: analyze.c would build a utility statement
CreateTableAs, pull the IntoClause out of the SelectStmt structure and
put it into the utility statement, and then proceed much as we do for
ExplainStmt (and for the same reasons).
