Hello, I'm looking for a better tutorial of how EXPLAIN works. I know Mr. Tom Lane wrote a "quick & dirty explanation"
andthat "plan-reading is an art that deserves a tutorial, and I haven't had time to write one". In which case I'd like
toknow if there's any other tutorials/resources.
I think I get the jist of it (an index scan is better than a seq scan?) but I'd like to read more. Does anybody have
anysuggestions?
