postgresql-9.5-postgis-scripts 2.2.1+dfsg-2 (powerpc binary) in ubuntu xenial

 PostGIS adds support for geographic objects to the PostgreSQL
 object-relational database. In effect, PostGIS "spatially enables"
 the PostgreSQL server, allowing it to be used as a backend spatial
 database for geographic information systems (GIS), much like ESRI's
 SDE or Oracle's Spatial extension. PostGIS follows the OpenGIS
 "Simple Features Specification for SQL".
 .
 This package contains SQL scripts to upgrade from earlier PostGIS
 versions for PostgreSQL 9.5 as well as Perl utility scripts.
