Thread: max / min explain

I've noticed that select max(the_primary_key) from some_table
does a table scan.  Is there any plan to implement max/min calculations
using index lookups if the appropriate index exists?

Thanks,

Alex.

Yes there is.  You can find it in the TODO list under
Performance -> Indexes
(http://www.postgresql.org/docs/todo.html).  It isn't
slated for the 7.1 release however.
