"Ask about your interview performance. It can get awkward." Maybe it's just me, but I always find that to ask for/give feedback is better(if asked), as recruiters almost never respond if you have not cleared the round and if there is opportunity to give feedback so that candidate has an idea on what to work on.

Also I have found that when asking for feedback, it can lead to interesting discussions which might make the interviewer change his/her mind.

This of course is personal preference...

while Postgress might be better if you use it 'as-is'.... community of MySQL is much better and the tools available are more mature... just goes on to prove that even if something is not-that-good.. it still might be successful,scalable and popular if there is a strong community behind it..
