One of the foreign data wrappers I included in the PostgreSQL 9.3 Windows FDW bag and PostgreSQL 9.4 Windows FDW bag is the www_fdw extension used for querying web services. Someone asked that since I didn't build curl with SSL support,
they are unable to use it with https connections. The main reason I didn't is that the EDB installs come with ssleay32.dll and libeay32.dll (even the 64-bit) which
are dependencies of curl when built with SSL support. I wanted to minimize the issue of distributing dlls that are packaged with Windows PostgreSQL installers already.
Though this article is specific to using www_fdw on Windows systems, many of the issues are equally applicable to other platforms, so may be worth a read if you are running into similar issues with using specialty SSL certificates on Linux/Unix/Mac.
One of the changes coming to you in PostGIS 2.2 are additional extensions. Two ones close to my heart are the address_standardizer (which was a separate project before, but folded into PostGIS in upcoming 2.2) and the SFCGAL extension for doing very advanced 3D stuff (was just an sql script in older versions, but made an extension in 2.2 and new functions added). We had a need to have address standardizer running on our Ubuntu box,
but since PostGIS 2.2 isn't released yet, you can't get it without some compiling. Luckily the steps are fairly trivial if you are already running PostGIS 2.1.
In this article, I'll walk thru just building and installing the address_standardizer extension from the PostGIS 2.2 code base. Though I'm doing this on Ubuntu,
the instructions are pretty much the same on any Linux, just replacing with your Linux package manager.
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I had mentioned how I build PL/V8 for PostgreSQL windows, and the instructions are a bit out of date., but I put more up to date instructions on my gist page.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
