I'm trying to deploy PostgreSQL + PostGIS for my ruby app. I followthis tutorial , but when I'm typing: CREATE EXTENSION PostGIS the terminal returns,

CREATE EXTENSION postgis;
CREATE : undefined command

my setup:

• POSTGRESQL 10.4
• Ruby 2.4.3

Answer 1

Where are you executing CREATE EXTENSION postgis ? This command has to be executed in the database via a PostgreSQL client, such as psql or pgAdmin . What you're getting is an error message from your console, which does not know this command.

Try this from your console:

psql -d yourdatabase -c "CREATE EXTENSION postgis"

Check the psql documentation for more details on how to connect to the database.
