Really? I'm kind of with Tom; I don't expect that keeping old
branches warning-free on new compilers is really workable. I think
the situation today is actually better than it was a few years ago, at
least for me. I get some warnings on older branches, but with other
toolchains I've used for PG hacking at other times, it was much worse.
I think that it might be worth back-patching some of the warning fixes
we've done would be a good idea. Like this one:
- if (!res || !res->cmdStatus || strncmp(res->cmdStatus, "INSERT
", 7) != 0)
+ if (!res || strncmp(res->cmdStatus, "INSERT ", 7) != 0)
return "";
I really don't see how back-patching that can hurt anything, and it
gets rid of a warning, so great. But not all cases are going to be so
clear cut, and getting all supported back-branches to compile warning
free on every contributor's current toolchain sounds like a treadmill
I don't want to get on.
