All that I wanted to do was look at EXPLAIN ANALYZE output that showed a parallel seq scan on my laptop, simply because I wanted to see a cool thing happen. I had to complain about it [1] to get clarification from you [2]. I accept that this might have been a somewhat isolated incident (that I couldn't easily get *at least* a little instant gratification), but it still should be avoided. You've accused me of burying the lead plenty of times. Don't tell me that it was too hard to prominently place those details somewhere where I or any other contributor could reasonably expect to find them, like the CF app page, or a wiki page that is maintained on an ongoing basis (and linked to at the start of each thread). If I said that that was too much to you, you'd probably shout at me. If I persisted, you wouldn't commit my patch, and for me that probably means it's DOA. I don't think I'm asking for much here.
