One thing I was wondering: has the SQL specification anything specific about the way vertical tabs should be parsed?
SQL has "whitespace", which includes any Unicode character with the White_Space property (which includes \v), and <newline>, which is implementation-defined.
So nothing there speaks against treating \v as a (white)space character in the SQL scanner.
In scan.l, you might want to ponder horiz_space: Even though \v is clearly not "horizontal space", horiz_space already includes \f, which is also not horizontal IMO. I think horiz_space is really all space characters except newline characters. Maybe this should be rephrased.
