Binary package “postgresql-10-postgis-2.4” in ubuntu bionic

Geographic objects support for PostgreSQL 10

 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".
 To create the PostGIS extensions in a PostgreSQL 10 database, the
 postgresql-10-postgis-2.4-scripts package must be installed as well.
