The current Tacker implementation does not support PostgreSQL,
and differences between the MySQL and PostgreSQL implementations can
cause errors in practice.
This patch implements PostgreSQL support through Tacker
and tacker-db-manage.
Note that UT/FT is not added because conventional tests can cover
this patch.
Implements: blueprint support-multidb-backend
