[OSGeo-Discuss] PostGIS 2.3.0beta1 release

[Faustin Gashakamba]

This is a very good development Regina.
I hope we will have a new edition of the "PostGIS in Action" soon as well. 
For beginners like me, it is one thing to go through the "what's new" in the official documentation and toddle through the arcane language therein and another thing to read a book written in a more humane style especially with Regina's touch!
Specifically, I would be interested to see how the Geography data type has been enhanced so far!

Thank you
Faustin
