Hi every body

it is possible to force to postgresql to use a certain index? I know that in mysql exits Force index (index_name) option for select queries
SELECT * FROM precalc FORCE INDEX (hladrb50101) ;

any of you have used this?

No. PostgreSQL will not allow you to do that. Not to mention, a SELECT * without a where clause will always scan the whole table so an Index would be useless.
