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.
