Postgis / Geodjango: Cannot determine PostGIS version for database

Question

I\'m attempting to launch a GeoDjango app. I\'ve installed Postgres & PostGIS using brew on Lion. I created a database using template_postgis: createdb -T template_pos

Answer 1

And in case the previous select returns an error, it may be that one particular version of PostGIS was installed on that database, that you updated Postgres.app to a newer version, that bundles a newer version of PostGIS. For example, after the recent update from Postgis 2.0 to 2.1

In that case, you can make a migration after copying back some libraries, like described in this ticket
