Dunno, as far as I know unions are pretyy efficient. An the other hand,
you could ofcourse do the following:
Add a column to the table which describes additional priviledges.
Write a trigger that uses that column and the current user-name to
determine whether a row should be returned.
Ah, just remembered, that won't work, cos you cannot define a trigger on
a select. Damned....
I don't know why Vadim didn't implement it, maybe it's just too dificult
to do, but I think there are certainly uses for such a trigger. Something
for 6.4???
