Well, if a "where clause" allows the system to use an index to search
for the subset of elements, that would reduce the number of pages that
have to be examined, thereby diminishing the amount of work.

Why don't you report what EXPLAIN ANALYZE returns as output for the
query with WHERE clause?  That would allow us to get more of an idea
of what is going on...

When  replying, it  is  often possible  to cleverly edit  the original
message in such a way  as to subtly alter  its meaning or tone to your
advantage while  appearing that you are  taking pains  to preserve the

of the matter.  -- from the Symbolics Guidelines for Sending Mail
