Thats correct, I choose this way because there will be a lot of entries
and it will grow pretty quickly, but maybe postgres will be able to
handle this?
If I went for a separate table it will contain over 3 milj. entries
within in a couple of weeks and still grow after that but not at the
same speed as the first weeks.
