> That means, if your block size was bigger, then you would have bigger
space allocated for one single record.
But if I INSERT second, third ... hundredth record in the table, the size
remains 8K.
So my point is that if one decides to increase block size, increasing
storage space is not so significant, because it does not set minimum
storage unit for a row.
