Yeah, if we were starting today, I'm sure we'd use C99 or C++ as our baseline and not arbitrarily exclude some language features. But ... we're not. The rule against declaration-after-statement was kept after significant discussion, which you can find in the archives if you look. We're not going to drop it just because one person shows up with a patch to do so. >>> It uses a Perl regex to search and replace!

Agreed. I think the odds of introducing bugs are near 100% if it's done without using a tool that actually understands the code semantics. regards, tom lane
