Luckily there is a way to do this.</p> <p>For this exercise, I will install PostGIS in the default schema and then demonstrate how to move it into another schema location.</p> <p>You can run these steps using psql or pgAdmin or any other PostgreSQL tool you want.</p> Continue Reading by clicking title hyperlink ..
