 Numeric values are physically stored without any extra leading or trailing zeroes. Thus, the declared precision and scale of a column are maximums, not fixed allocations. (In this sense the `NUMBER` type is more akin to `VARCHAR(N)` than to `CHAR(N)`.) The actual storage requirement is two bytes for each group of four decimal digits, plus three to eight bytes overhead.
 
-In addition to ordinary numeric values, the `NUMBER` type allows the special value NaN, meaning “not-a-number”. Any operation on NaN yields another NaN. When writing this value as a constant in an SQL command, you must put quotes around it, for example U`PDATE table SET x = 'NaN'`. On input, the string `NaN` is recognized in a case-insensitive manner.

 !!!Note
 In most implementations of the “not-a-number” concept, `NaN` is not considered equal to any other numeric value (including `NaN`). In order to allow numeric values to be sorted and used in tree-based indexes, PostgreS treats `NaN` values as equal, and greater than all non-`NaN` values.

 The type names `SERIAL` and `SERIAL4` are equivalent: both create integer columns. The type names `BIGSERIAL` and `SERIAL8` work the same way, except that they create a bigint column. `BIGSERIAL` should be used if you anticipate the use of more than 2147483648 identifiers (2 to the 31st power)over the lifetime of the table. The type names `SMALLSERIAL` and `SERIAL2` also work the same way, except that they create a `SMALLINT` column.
 
-The sequence created for a `SERIAL` column is automatically dropped when the owning column is dropped. You can drop the sequence without dropping the column, but this will force removal of the column default expression.
