I think this might have advantages purely from the standpoint of new compilers possibly offering useful warnings we don't get now. But if we only go this far, I'm pretty dubious that it really helps people to develop extensions in C++. Almost invariably, if you ask *why* they want to do that, you'll get an answer involving C++ libraries that are not going to play very nice with our error handling or memory management conventions. I do not see how we could C++-ify the error handling without making a complete break with C compilers ... which is a step I don't really want to take. The whole thing would make a lot more sense given a credible design for error handling that keeps both languages happy. A lot of the other things people have muttered about, such as heavier use of inline functions instead of macros, don't particularly need C++ at all. regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
