Our policy so far has been to add PGDLLIMPORT to variables for which someone makes a case that an extension would have a reasonable use for it. The bar's not terribly high, but it does exist. The idea of just doing a blanket s/extern/extern PGDLLIMPORT/g has been discussed and rejected, because we don't want to commit to supporting absolutely every global variable as something that's okay for extensions to touch. So if you've got specific proposals (such as "Mode"), bring them up on pgsql-hackers. regards, tom lane
