DB Error when clicking Submissions on Admin page

I have just installed OJS 3.1.0-1 for the first time, and I am using a PostreSQL database. The installation had no errors and I have been able to successfully save settings for the journal. However, when I click on the Submissions tab of the Admin page, I get the following error displayed as the only text on the resulting webpage:

DB Error: ERROR: column “s.locale” must appear in the GROUP BY clause or be used in an aggregate function LINE 1: select “s”.*, COALESCE(stl.setting_value, stpl.setting_value… ^

Any recommendations of how to solve or debug this problem?


Figured out that my shared hosting service runs PostgreSQL 8.4.20, which does not meet the minimum system requirements for OJS 3.x. Changed the database to MySQL and the problem was resolved.
