We are pleased to provide binaries for file_textarray_fdw and odbc_fdw for PostgreSQL 13 Windows 64-bit.
To use these, copy the files into your PostgreSQL 13 Windows 64-bit install folders in same named folders and then run CREATE EXTENSION as usual in the databases of your choice. More details in the packaged README.txt

For those folks on windows who want to do http gets and posts directly from your PostgreSQL server, we've made binaries for the http extension for PostgreSQL Windows.
These should work fine on both PostgreSQL EDB windows distributions as well as the BigSQL windows 64 distributions.
Instructions in the ReadMe.txt for where to copy the files to for each distribution. Caution should be taken especially with BigSQL to not overwrite existing BigSQL files.
Many of the files in this already exist in the BigSQL distribution since we both compile using the Mingw64 chain.
If you have PostGIS already installed, many of these files you will also already have since things like the libcurl and PCRE are also packaged with PostGIS.

I gave a talk at PGConf US 2019 on some of the many ways you can load data into PostgreSQL using open source tools.
This is similar to the talk I gave last year but with the addition of the pgloader commandline tool and the http PostgreSQL extension.
HTML slides PDF slides
Even though it was a talk Not much about PostGIS, but just tricks for loading data, I managed to get a mouthful of PostGIS in there.

We recently installed PostgreSQL 11 on an Ubuntu 18.04 using apt.postgresql.org. Many of our favorite extensions were already available via apt (postgis, ogr_fdw to name a few), but it didn't have the http extension we use a lot. The http extension is pretty handy for querying things like Salesforce and other web api based systems. We'll outline the basic compile and install steps. While it's specific to the http extension, the process is similar for any other extension you may need to compile.

PostGIS 2.5.1 was released on November 18th 2018 and I finished off packaging the PostGIS 2.5.1 windows builds and installers targeted for PostgreSQL EDB distribution this weekend and pushing them up to stackbuilder. This covers PostgreSQL 9.4-11 64-bit and PostgreSQL 95-10 (32bit).
Note that PostGIS 2.5 series will be the last of the PostGIS 2s. Goodbye PostGIS 2.* and start playing with the in-development version of PostGIS 3. Snapshot binaries for PostGIS 3.0 windows development are also available on the PostGIS windows download page. These should work for both BigSQL and EDB distributions.

At PGOpen 2018 in San Francisco, we gave a talk on 10 ways to load data into Posgres. This is one of the rare talks where we didn't talk much about PostGIS. However we did showcase tools ogr_fdw, ogr2ogr, shp2pgsql, which are commonly used for loading spatial data, but equally as good for loading non-spatial data. Below are the slide links.

Most of our use-cases for the built-in json support in PostgreSQL is not to implement schemaless design storage, but instead to remold data.
Remolding can take the form of restructuring data into json documents suitable for web maps, javascript charting web apps, or datagrids. It also has uses beyond just outputting data in json form. In addition the functions are useful for unraveling json data into a more meaningful relational form.
One of the common cases we use json support is what we call UNPIVOTING data.
We demonstrated this in Postgres Vision 2018 presentation in slide 23.
This trick won't work in other relational databases that support JSON because
it also uses a long existing feature of PostgreSQL to be able to treat a row as a data field.

Leo and I attended PostgresVision 2018 which ended a couple of days ago.
We gave a talk on spatial extensions with main focus being PostGIS. Here are links to our slides PostgresVision2018_SpatialExtensions HTML version
PDF.
Unfortunately there are no slides of the pgRouting part, except the one that says PGRouting Live Demos because Leo will only do live demos. He has no fear of his demos not working.
Side note, if you are on windows and use the PostGIS bundle, all the extensions listed in the PostGIS box of the spatial extensions diagram, as well as the pointcloud, pgRouting, and ogr_fdw are included in the bundle.

We've updated our binaries for PostgreSQL 10 windows, both 32 and 64-bit. The 64-bit should work fine with EnterpriseDb windows as well as BigSQL.

PostgreSQL JSQuery extension Windows binaries
The JSQuery extension is a PostgreSQL extension developed by Postgres Professional. You can get the source code and instructions for use at
https://github.com/postgrespro/jsquery. JSQuery is a fairly easy compile install if you are on a Nix system.
It provides more query functionality and additional index operator classes to support for JSONB than you get in built in PostgreSQL.
It is supported for PostgreSQL 9.4 and above.
We've built windows binaries for PostgreSQL 64-bit 9.4, 9.5, 9.6, and 10beta1. The 9.4 64-bit will only install on the EDB PostgreSQL 9.4 64-bit distribution.
The 9.5 and 9.6 are compatible with both PostgreSQL EDB and BigSQL distributions. The 10 has only been tested on BigSQL, but should work on EDB when it comes out. We should have 32-bit versions later and will link to those here.

A while ago when Foreign Data Wrappers in PostgreSQL was a fairly new thing, we talked about the ODBC_FDW foreign data wrapper. Since then, people have been asking us how to get the ODBC FDW to work on newer PostgreSQL.
Sadly the ODBC_FDW was stuck in time not having updated to newer FDW API standards.
Our recommendation was just to use OGR_FDW, which many distributions both Linux and Windows have compiled OGR_FDW with ODBC support.
True that OGR_FDW is coined as a spatial data wrapper, but the reality is spatial data rarely lives apart from regular attribute data so a good spatial vector driver supports both vector data and bread and butter data types. OGR_FDW is still our go to for working with spreadsheets and folders of CSV files.
Recently the fine folks at Carto patched the ODBC FDW to work with PostgreSQL 9.5. I do hope they accept my modest patch to make it work with PostgreSQL 9.6 as well.
So now 2 FDWs to choose from for connecting to ODBC datasources. Which one is better? The answer as most always is IT DEPENDS.

We gave a PostGIS Intro Training and a PostGIS talk at PGConfUS 2016 in Brooklyn, New York and just got back. A number of people asked if we'd make the slides and material available. We have these posted on our presentation page: http://www.postgis.us/presentations and will be putting on the PostgreSQL Wiki as well in due time. There will be a video coming along for the talk, but the training was not recorded.
We also have two more talks coming up in North Carolina in Early May at FOSS4G NA 2016 - one on PostGIS Spatial Tricks which has more of a GIS specialist focus than the top 10 talk we gave, but there will be some overlap. The other talk is a topic a couple of people asked us in training and after our talk, on routing along constrained paths. If you are attending FOSS4G NA 2016, you won't want to miss our talk pgRouting: A Crash Course which is also the topic of our upcoming book.
Just like FOSS4G NA 2015, there is a pgDay track which is PostgreSQL specific material, useful to a spatial crowd, but not PostGIS focused.

Someone reported recently on PostGIS mailing list, that they were unable to install PostGIS 2.2.1 bundle or PostGIS 2.2.2 binaries on a clean PostgreSQL 9.5.2 install.
Someone also complained about PostgreSQL 9.3 (though not clear the version) if that is a separate issue or the same. I have tested on PostgreSQL 9.5.2 Windows 64-bit and confirmed the issue. The issue does not affect PostgreSQL 9.5.1 and older. I haven't confirmed its an issue with the 32-bit installs, but I suspect so too. This
issue will affect OGR_FDW users and people who used our compiled WWW_FDW.
