I also noticed this the other day while messing with the plpgsql lexer:

/* ----------
* The keyword rules
* ----------
*/
:= { return K_ASSIGN; }
= { return K_ASSIGN; }

This code goes back to the original scan.l from 1998. I'm guessing it has
always worked, but was never documented -- but I've been known to be wrong
sometimes ;-). Hopefully Jan will chime in.
