Hello,
I'm looking for a better tutorial of how EXPLAIN works. I know Mr. Tom Lane
wrote a "quick & dirty explanation" and that "plan-reading is an art that
deserves a tutorial, and I haven't had time to write one". In which case I'd
like to know 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 any suggestions?
