DAO builds

[Yevgeny Zaspitsky]

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
