Create PostgreSQL Extension Network (PGXN) Release

Artifacts are uploaded to the Apache MADlib extension product location https://pgxn.org/dist/madlib/:

Here are the general steps (used for 1.12 release)::

git clone git@github.com:apache/madlib.git
cd madlib
git branch MADLIB-1.12 rel/v1.12
git checkout MADLIB-1.12
mkdir build; cd build
make pgxn
Upload Release through PGXN Manager at https://manager.pgxn.org. The built artifact will reside in deploy/PGXN/madlib-pgxn-2.0.0.zip in your build directory.

Verification steps:

sudo easy_install pgxnclient
sudo chmod a+w /usr/local
sudo rm -rf /usr/local/madlib
pgxn install madlib
dropdbmadlibtest; createdbmadlibtest; /usr/local/madlib/bin/madpack -s madlib -p postgres install
/usr/local/madlib/bin/madpack -s madlib -p postgres install-check
