Hi,
we recently try to build a costumer index type around 8.3, for now
want to teach
planner to pick up specific index for our query, so we'd like to use
some do***ent
about how a query tree trun into different query plan and how to
decide which one
to use. Is there any do***ent about that? Any hints will be great
appreciated!
thanks and best regards
