This document describes the process for installing PostGIS and creating a template PostGIS database. It is assumed that PostgreSQL has been installed. If it hasn't, please refer to the PostgreSQL page.

Installing PostGIS

  • Install PostGIS.
$ su
$ pacman -Sy postgis

Creating a Template PostGIS Database

  • Become the postgres user.
$ su
$ su - postgres
  • If you haven't created a superuser for accessing PostgreSQL, you may want do that now. You will be prompted for granting permissions to that user.
$ createuser [username]
  • Create a new database called "template_postgis".
$ createdb -O [username] template_postgis -E UTF-8
  • PostGIS requires the pl/pgSQL language to be installed on a database.
$ createlang plpgsql template_postgis
  • Load the PostGIS spatial types for PostgreSQL and spatial reference systems. "lwpostgis.sql" and "spatial_ref_sys.sql" are part of the installation of PostGIS, and may reside somewhere else besides "/usr/share" depending on the installation.
$ psql -d template_postgis -f /usr/share/lwpostgis.sql
$ psql -d template_postgis -f /usr/share/spatial_ref_sys.sql

Creating a PostGIS Database From the Template

  • It's common practice to reserve a bare template for creating new PostGIS databases. As a PostgreSQL superuser, the following command will create a new database:
$ createdb -T template_postgis [new_postgis_db]
