Attached patch introduces --custom-initialize option that allows us to
specify the initialization step and its order. For example, If you
want to skip building primary keys you can specify
--custom-initialize="create_table, load_data, vacuum". Since each
custom initialization commands is invoked in specified order, for
example we also can create primary keys *before* loading data. The
data-generation is doing on client side, so progress information for
initialization is still supported.
