unreserved according to the grammar. The list of unreserved words has gotten extensive enough that the unnecessary quoting is becoming a bit of an eyesore. To do this, add knowledge of the keyword category to keywords.c's table. (Someday we might be able to generate keywords.c's table and the keyword lists in gram.y from a common source.) For the moment, lie about WITH's status in the table so it will still get quoted --- this is because of the expectation that WITH will become reserved when the SQL recursive-queries patch gets done. I didn't force initdb because this affects nothing on-disk; but note that a few regression tests have changed expected output.
