> Postgres won't even let your force an execution plan and ignores hints
Finally, an actual technical argument. I agree that PostgreSQL's absolute insistence on trusting the query optimiser to Do The Right Thing is weird and annoying (despite being sound general strategy). It even seems to contradict its own general spirit of being on the whole extremely customisable -- you can make your own data types, operators, indexing data structures, complete scripting language plugins... but not, ya know, a way to 100% guarantee that this here query will use this here execution plan.
