Check for PostGIS support

Execute the following command and check the output to find out if PostGIS is installed and which version is in use:

$ psql -c "SELECT name, default_version,installed_version FROM pg_available_extensions WHERE name LIKE 'postgis%' ;"

Here is an example of the output:

     name       | default_version | installed_version
------------------+-----------------+-------------------
postgis          | 2.0.0           |
postgis_topology | 2.0.0           |
(2 rows)

To check which version of PostGIS is being loaded by the database, execute the following command:

$ psql yourdatabase -c "SELECT PostGIS_Full_Version()"

Here is an example of the output:

postgis_full_version
