To install first create a postgresql database using createdb, psql, or pgAdmin
Copy the files from this zip file to same named folders in your PostgreSQL install.

Install PostGIS 2.1 or 2.2 or 2.3 or 2.4 using:
CREATE EXTENSION postgis;

If you have multiple versions of PostGIS and want to force a particular version do:
--For latest stable
CREATE EXTENSION postgis VERSION "2.3.3";

--For latest dev
CREATE EXTENSION postgis VERSION "2.4.0dev";

Then install pgRouting:

CREATE EXTENSION pgrouting;


If updating from old pgrouting use instead
ALTER EXTENSION pgrouting UPDATE;

If you are updating from a development version and UPDATE fails, do:

DROP EXTENSION pgrouting;
CREATE EXTENSION pgrouting;
