This change was forced by new features to support SQL9x INTERVAL syntax.
Since the full syntax allows constants of the form "INTERVAL 'val' DAY
TO MINUTE" I had to change the main parser to make INTERVAL a reserved
word, as is specified in SQL9x.

Using internal conversion functions to force type is not recommended (or
at least shouldn't be). You probably know that CAST('string' AS
INTERVAL) should work for you, and is SQL9x compliant.
