Support for ROW_NUMBER() OVER() as an alias for ROWNUM() for compatibility with PostgreSQL and Apache Derby.

The syntax for CREATE TABLE ... AS SELECT ... has been changed: options such as NOT PERSISTENT are now before the query (AS SELECT), because otherwise they might be interpreted as a part of the query.

VALUES is now supported as a standalone command and as a table source: SELECT * FROM (VALUES(1, 'Hello'), (2, 'World')) AS V;

A query with an explicit LIMIT 0 will now return no rows (so far it meant no limit), which is compatible with PostgreSQL and MySQL. A negative limit value (as well as LIMIT NULL) mean no limit (so far a negative limit meant a limit of one row).
