DAO builds

Hi, Most of the DAO tests on Jenkins (http://jenkins.ovirt.org/job/ovirt-engine_master_dao_unit_tests_gerrit/) fail with the following message: Could not open JDBC Connection for transaction; nested exception is org.postgresql.util.PSQLException: Connection refused. Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections. Could you please look into the problem? Thanks in advance, Yevgeny
