I'm still in the middle of building packages for our clients for the packages that aren't normally distributed for windows to make upgrading to PostgreSQL 9.4 smooth. One of those is PL/V8 which we use for some custom functions.
I had mentioned how I build PL/V8 for PostgreSQL windows, and the instructions are a bit out of date., but I put more up to date instructions on my gist page. I tend to use gist a lot as a public scrap book with hopes someone else can learn from my toils and save them some trouble. At some point I should probably get more organized with my scrapbooks.
As stated in last article, I've packaged FDW binaries for PostgreSQL 9.3 windows 32-bit and 64-bit and added in the ogr_fdw one. These we've tested with the standard EDB Vc++ built PostgreSQL windows installs and work fine with those.
This package is an updated list from ones we've distributed before that includes ogr_fdw and recompiled with latests source from www_fdw and file_textarray
