I checked http://codesearch.debian.net and found only a couple of extensions that #include guc_tables.h at all, so I'm satisfied that the struct config_generic ABI issue is tolerable. Recompiling after beta3 would be enough to fix any problem there, and it's hard to believe that anyone is trying to ship production-ready v15 extensions already. The aspect that is a bit more debatable is whether to trouble with a set_config_option() wrapper to avoid the API break in v15. I think we'd still be making people deal with an API break in v16, so making them do it this year rather than next doesn't seem like a big deal ... but maybe someone wants to argue it's too late for API breaks in v15? regards, tom lane
