I second that. Given the 20,30 or whatever years postgres dealt with all kinds of file systems, hard drive failure codes and what not I would not recommend to jump to any of the newer contenders without a very good reason. I am not biased towards postgres per se but of all the newer components that the digital world can offer I like to be as secure as possible when it comes to the question whether or not my data was actually Written to a disk. It’s a surprisingly hard problem when you have to work with thousands of connections.
