and there's optimization with this flag? i see that equal could be
optimized cause if we found 1 row we can return to user that row and stop
select

in other words, if i see a index with primary key or unique columns, could
i change the index to unique and get some kind of performace? today i think
not ,cause unique key check if it's really unique (for example at
insert/update/replace), i'm wrong?
