Answer 1

Why aren't you just using?

CREATE EXTENSION postgis;

It's universal across all platforms for PostGIS 2.0+ unless your distro for some crazy reason did not include raster.

pgAdmin New extension drop down -- in extension section, shows extensions you have available you have not yet installed in your db.
