[ckan-dev] Backup problems using paster db dump with spatial extension

Thu Oct 16 10:41:06 UTC 2014

David,

These spatial tables aren't accessible unless you run it as
Postgresql's superuser called 'postgres'. By default, the unix 'root'
user isn't a superuser for Postgresql (I'm sure they have their
reasons!).

The solution is to use 'sudo -u postgres' before the
paster/pgdump/psql commands. So in your case:

$ sudo -u postgres /usr/lib/ckan/default/bin/paster db dump
--config=/etc/ckan/default/
production.ini my_ckan_database.pg_dump

If you can confirm this works, I'll update the docs.

David
