First, I'm neither for nor against rewriting PostgreSQL in C++. But I wonder whether it would really pay for the cost. I'm worried about these, for example: * Wouldn't it increase the coding and testing burdon? Coding and testing in C, and coding and testing in C++. PostgreSQL seem to have many features to develop, and I'm not sure C++ will help to speed up the development of them. * Would it really attract more developers of PostgreSQL itself, not extensions? FYI, Tiobe Index says C is nearly twice as popular as C++. http://www.tiobe.com/tiobe-index/ * Wouldn't it distance some developers if they don't want to learn C++? As Christopher said, C++ is old and there are many newer languages that attract developers -- C#, Swift, Go, Java, JavaScript, etc. I wonder whether recent developers want to spend time in learning complex C++ now. I learned C++ because it is still the most popular language in game development, but maybe I would not want to learn C++ anymore if I didn't know C++.
