A composite type represents the structure of a row or record; it is essentially just a list of field names and their data types.

Serial: represents an auto-incrementing numeric value that takes 4 bytes and can store numbers from 1 to 2147483647. PostgreSQL has a rich set of native data types available to users. The value of this type is formed by auto-incrementing the value of the previous string. This data type is used to store characters of limited length. PostgreSQL offers three character data types: CHAR(n), VARCHAR(n), and TEXT. This data type is used to store character of unlimited length. It is represented as text in PostgreSQL.
