you didn't understand me. I know so operator <* isn't supported now.
I prefere SQL spec behave too. But what I wont:
a <* b ~ ai <= bi and one ai < bi => true ; if one ai > bi => NULL; else
false
but this behave is from some views really chaotic. This comparation is used
in operation research, but propably is far to ideas ANSI SQL. It was only
idea.
