Yes, I know that feeling! I have been using as well the Assert(false) and the upgrade-to-PANIC tricks a couple of times, so being able to get more easily backtraces would be really nice.
Sometime back I'd suggested an idea to be able to dynamically manage log levels for elog messages [1]. That did not invoke much response, but I still believe some such facility will be very useful for debugging production systems. Now I concede that the POC patch that I sent is horribly written and has a bad UI, but those can be improved if there is interest. Given the lack of response, I suspect there is enough interest in the feature though.
