I'm having a difficult time finding documentation on EXPLAIN PLAN stats. For example, in
' -> Nested Loop Left Join (cost=0.43..1415.06 rows=2 width=1377) (actual time=0.093..0.093 rows=0 loops=1)'
what does 0.43..1415.06 mean? Is that a range? If so, it seems rather pointless, like saying "somewhere between 0 and infinity".
Also, is there a way to tell the query planner to limit the search for the best plan on a per statement basis. I know that this exists as a config parameter but I think that applies to the entire database. I have a query that takes 9 times more time to plan than it does to execute.
Tia,
