cannot create extension without superuser role

Question

I\'m trying to run unit tests in Django, and it creates a new database. The database has postgis extensions and when I regularly create the database, I use \"CREATE ExTENSIO

Answer 1

You can also install postgis to the template1 database template which is inherited by default by all newly created database.

$ psql -U postgres -d template1 -c "CREATE EXTENSION postgis;"

All new databases created from this point will have the postgis extension installed, including Django's test database, unless they specify a different template when creating a database.

If having postgis installed to all newly created databases is not desirable, you can create a new template, install postgis in it, and then have Django use this template when creating the test database.

$ createdb template_postgis;  # create a new database
$ psql -U postgres -c "UPDATE pg_database SET datistemplate = TRUE WHERE datname = 'template_postgis';"  # make it a template
$ psql -U postgres -d template_postgis -c "CREATE EXTENSION postgis;"  # install postgis in it

Then in Django settings:

...
DATABASES = {
    'default': {
        ...
        'TEST': {
            'TEMPLATE': 'template_postgis',
        },
    },
}
