Description of problem:
    The DWH is unable to insert new records to the ovirt-history-db as some of the sequences next value contain higher number than the primary key can store.

Version-Release number of selected component (if applicable):
	rhevm-dwh-3.4.0-10.el6ev.noarch

How reproducible:
	100% if the service runs for logn time.

Steps to Reproduce:
	This is not easy to reproduce as it need really long time to insert enough
	records to the DB.

	It can be triggered by the following command:

		SELECT pg_catalog.setval('host_interface_history_seq1', 2147491275, true);

Actual results:

	The data are not collected any more

Expected results:

	The collection continues

Additional info:

The sequences are created in the following way

	CREATE SEQUENCE host_interface_history_seq1                                     
	     START WITH 1                                                                                                        
	     INCREMENT BY 1                                                                                                      
	     NO MAXVALUE                                                                                                         
	     NO MINVALUE                                                                                                         
	     CACHE 1;

There is not max value set. The primary key of the related table is an integer
(-2147483648 to +2147483647)

It would be more suitable to use bigserial for autoincrementing values.
We may also set the max value and set CYCLE option for tables where we
periodically remove the old content.
