Each column gets a percentage to reserve. 0% means the column will always be
populated with a value that never changes size. 100% means the column will be
inserted with a null, then updated with a full-size value.
Default values:
-) Surrogate keys get 0% reserve
-) LOG and EFF tables should reserve 0%??? because no updates are allowed on these rows

The default value for required columns is 5. The default value for
non-required columns is 10. Note: space must also be reserved for values that
are updated with a larger size value after the initial insert.

For improved calculations, "init_avg_len" is needed in tab_cols to capture the
average length of column data in an inserted record.
