libjson0-dev is apparently deprecated and the correct package to install is now libjson-c-dev

How to install PostGIS 2.4 on Debian 9.x (stretch) from source

Prerequisites

Several components are needed, which can either be built from source or installed from pre-built packages, as shown below. For a quick start, there are official Docker images for Postgres here https://hub.docker.com/_/postgres/ For some features to be enabled (like parallel query support for spatial joins), Postgres 10 is required, but most features work with 9.6.

With a Docker v10 image, Postgres is already installed, but the server-dev package is required:

sudo apt-get install postgresql-server-dev-10

Without the Docker image, start by first installing the Postgres package:

sudo apt-get install postgresql-9.6 postgresql-server-dev-9.6 

Then for either approach, install the prerequisite packages for PostGIS using:

sudo apt-get install build-essential libxml2-dev libgdal-dev libproj-dev libjson-c-dev xsltproc docbook-xsl docbook-mathml

Build GEOS 3.7.x

PostGIS 2.4 is best used with GEOS >= 3.7 for several new features, however Debian stretch only has GEOS 3.5.1 available in system packages, so if you want to enable all features, GEOS needs to be built from source. If you don't need the new features(e.g ST_FrechetDistance), you can instead install the available version of GEOS sudo apt-get libgeos-dev.

There are multiple ways to build GEOS from source, but this is the simplest (Note: currently version 3.7 is only available in the nightly build. When 3.7 is released, switch to that):

wget http://geos.osgeo.org/snapshots/geos-20170817.tar.bz2
tar xfj geos-20170817.tar.bz2
cd geos-20170817
./configure
make
sudo make install
cd ..

Build PostGIS

wget http://postgis.net/stuff/postgis-2.4.0dev.tar.gz
tar xfz postgis-2.4.0dev.tar.gz
cd postgis-2.4.0dev

A basic configuration for PostGIS 2.4, with raster and topology support:

./configure
make
sudo make install
sudo ldconfig
sudo make comments-install

Spatially enabling a database

Connect to your database using pgAdmin or psql, and use the commands to add the PostgreSQL extensions. To add PostGIS with raster support:

CREATE EXTENSION postgis;

To add topology support, a second extension can be created on the database:

CREATE EXTENSION postgis_topology;

Troubleshooting

If you already had Postgres running before the build, make sure to restart:

sudo /etc/init.d/postgresql restart
