planner document?
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 document
about how a query tree trun into different query plan and how to
decide which one
to use. Is there any document about that? Any hints will be great
appreciated!
thanks and best regards
