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.
