We are pleased to provide binaries for file_textarray_fdw and odbc_fdw for PostgreSQL 12 Windows 64-bit.
To use these, copy the files into your PostgreSQL 12 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 are designed to work with PostgreSQL EDB windows distributions.
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.
