RHEV Reports - Cannot access portal after changing DB pasword

Issue

• After changing RHEV's postgresql password, cannot access RHEV Report Portal and the attempts are immediately redirected to RHEV Manager's main page.

# cat /var/log/ovirt-engine/jasperserver.log 
....
Caused by: javax.resource.ResourceException: Could not create connection
    at org.jboss.jca.adapters.jdbc.local.LocalManagedConnectionFactory.getLocalManageConnection(LocalManagedConnectionFactory.java:282)
    at org.jboss.jca.adapters.jdbc.local.LocalManagedConnectionFactory.createManageConnection(LocalManagedConnectionFactory.java:240) 
    ....
Caused by: org.postgresql.util.PSQLException: FATAL: password authentication failed for user "postgresql"
    at org.postgresql.core.v3.ConnectionFactoryImpl.doAuthentication(ConnectionFactoryImpl.java:291)

• Except this, all RHEV-M Admin Portal works and accessing 'engine', 'ovirt_engine_history', 'rhevmreports' databases with psql command works
