PostGIS 2.2 is planned to reach feature freeze June 30th 2015 so we can make the September PostgreSQL 9.5 curtain call with confidence. Great KNN enhancements for PostgreSQL 9.5 only users. I've been busy getting all my ducks lined up. A lot on tiger geocoder and address standardizer extension to be shipped with windows builds, story for later. One other feature we plan to ship with the windows PostGIS 2.2 builds is the ogr_fdw ogr_fdw Foreign data wrapper extension. I've been nagging Paul Ramsey a lot about issues with it, this in particular https://github.com/pramsey/pgsql-ogr-fdw/issues/25, and after some prodding, he finally put his nose in and fixed them and pinged Even Rouault for some help on a GDAL specific item.
Needless to say, I've been super happy with the progress and support I've gotten with ogr_fdw development and really enjoying my ogr_fdw use. The XLSX reading a file saved after the connection was open required a fix in GDAL 2.0 branch (which missed GDAL 2.0.0 release, so because of this, this new package contains a GDAL 2.0.1ish library. Hopeful GDAL 2.0.1 will be out before PostGIS 2.2.0 comes out so I can release without guilt with this fix.
If you have the OGR_FDW we discussed in OGR FDW Windows first taste built with ODBC support,
then you can access most any ODBC datasource from PostgreSQL. This is especially useful for Windows users. Two of the data sources I've been experimenting with are SQL Server
and MS Access. In this article, I'll demonstrate how to connect to MS Access with PostgreSQL running on a windows box. I think there is an Access driver for Unix/Linux most robust utilizes java. I won't go there.
Registry hack should no longer be needed for PostGIS 2.2 ogr_fdw bundle and up since these come packaged with newer GDAL libraries that have the fix.
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
This christmas I received something very special from Paul Ramsey and Even Roualt
as detailed in Foreign Data Wrappers for PostGIS.
It's been something I've been patiently waiting for for 4 years. I think it has a few issues I'm working to replicate, but overall it's much faster than I expected and pretty slick.
So why is ogr_fdw so special, because GDAL/OGR is an avenue to many data sources, NOT JUST GEOSPATIAL. It's the NOT JUST that I am most excited about. Though the focus is geospatial you can use it with non-geospatial datasources,
as we described a long time ago in OGR2OGR for data loading
