I happened to notice today that the owner of buildfarm member narwhal is trying to revive it after a long time offline, but it's failing in the 9.3 branch (and not attempting to build HEAD, yet). The cause appears to be that contrib/postgres_fdw is referencing the DateStyle and IntervalStyle variables, which aren't marked PGDLLIMPORT. Hm, well, that would be an easy change ... but that code was committed last March. How is it that we didn't notice this long ago?
What this seems to indicate is that narwhal is the only buildfarm animal that has a need for PGDLLIMPORT marks on global variables that are referenced by extensions. Furthermore, nobody has attempted to build 9.3 on a platform that needs that (or at least they've not reported failure to us). According to the buildfarm database, narwhal is running a gcc build on Windows 2003. That hardly seems like a mainstream use case. I could believe that it might be of interest to developers, but clearly no developers are actually running such a build. I think we should give serious consideration to desupporting this combination so that we can get rid of the plague of PGDLLIMPORT marks. Obviously this would depend on confirming that there are no more-interesting Windows build methods that require it --- but if there are any, I'd sure demand that there be an active buildfarm instance to keep us from breaking the case again in future.
