ain't btree with duplicates very similar to btree-index thing, because 
btree-index also supports duplicates?

why do you think so? cursor are probably biggest difference between CL-SQL 
and postmodern -- instead of reading everything and sorting on lisp side, we 
use sorting done by postgresql, and pick stuff in portions, i.e. cursor-next 
is something like:

 SELECT k, v FROM btree11 WHERE ((k = $1) and (v > $2)) OR (k > $1) LIMIT 10
