[galaxy-dev] Postgresql database not working

Hi all, I just installed the newest version of Galaxy with: hg clone https://bitbucket.org/galaxy/galaxy-dist I use Apache httpd as proxy and ldap authentication. If I leave the database as it is set by default everything works fine. sqlite:///./database/universe.sqlite?isolation_level=IMMEDIATE But if I now change to postgres my histories cannot be fetched. I'm not sure how to explain it, but every time I refresh the history panel a new history is created. The database connection is fine, it also creates the history entries in the database, but something is wrong. Has someone an idea or can help? Thanks a lot! Cheers, Sajoscha
