SERIAL is the same as makeing a column and then setting the default value
to a sequence. If you insert and don't specify the column that is of type
serial it will have a new unique value on each insert. The datatype in a
serial
column is an int4.

These things are explained with little effort. Granted sometimes these
are easily answered by consulting documentation, but sometimes all
anyone is looking for is a simple, quick answer.
