Thread: Where's that doc on plans ?
A few days ago I read a very interesting doc about postgres' query planner, how to read an EXPLAIN plan, how is a cost calculated, etc. but I can't find it anymore. Anyone has an idea ?

If you're not thinking of the EXPLAIN tutorial in http://www.postgresql.org/devel-corner/docs/postgres/performance-tips.html then I'd be interested to know what you *are* thinking of... regards, tom lane
