Looks much better to me, but the use of strcmp() doesn't look good.
ISTM that stmtType is mostly used for error messages. I think you
should add some kind of identifier (such as the original parser Node)
into the CreateStmtContext so that you can do a IsA() test instead -- a
bit more invasive as a patch, but much cleaner.

Also the error messages need more work.
