Hi
Thanks for this :) - I have change the ckanext/datastore/plugin.py file and now the system starts and the ckan page does work.
But, I can find any good info about how to use the datastore compared to use the filestore, do I have to have both enabled? How do I put data to the datastore? Do I need the datastorer plugin or is there another way to use it?
Would be nice if someone could clear this out for me :)

Hi,
looks like your postgres version does not have support for the concat function. I submitted a pull request [1] that replaces the concat function. You could either cherry-pick the commit, get the patch or wait for it to be in master.
I'm sorry that we did'n catch that during our tests.
Cheers,
Dominik
