Data types
In computer science, data type is a combination of values and operations that one variable
can perform. There are a large number of data types available such as integer, float,
Boolean, Array, Hash, and many others. PostgreSQL is no different; you have a collection
of data types available by default, such as numeric, monetary, character, binary, date/time,
Boolean, enumerated, and many others.
In some cases, other kinds of data types are necessary and they aren't installed by default
on PostgreSQL. In this section, you will discover the power of some important extensions
for data types.
