Hi, all. I found the problem - it was merely a poorly written query, which for some reason was less terrible on my laptop. Looking at http://explain.depesz.com/ helped me solve the issue. Performance is now back to normal. It seems this was a classic case of pebcak. Thank you for your help and time!

Trying to fix this problem, I copied the database (using pg_dump) to my laptop, and reran tests there. The same queries perform perfectly on my laptop. We can but guess, but... Quite possibly your laptop is not actually a poorer machine for single uncomplicated queries. If it's cores are faster than the test servers, than your laptop would out-perform the server for such queries. Once you get other users starting to run queries as well, turning the load into a parallel load, the server will probably turn out faster again. -- If you can't see the forest for the trees, Cut the trees and you'll see there is no forest.
