A data type (or) only types refers to the specific type of data that the variable holds. Moreover, these include the date, timestamps, varchar, and some other formats.

1. PostgreSQL Data Types
What is the data type?
A data type (or) only types refers to the specific
type of data that the variable holds. Moreover,
these include the date, timestamps, varchar, and
some other formats.
The PostgreSQL is a database that manages multiple
values of data.

2. Numeric Datatypes
PostgreSQL supports two types of Numeric datatypes, including integers and
Floating point numbers.

3. Monetary data types
This is the detailed data that the database provides. Here in this data type, numeric
values, int and bigint can be modified into money. So now many person say that we
can use Float datatype. But this is not recommended to manage money due to the
potential for rounding bugs.
Character data types
The following table includes the PostgreSQL character datatypes.

4. Date/time data type
The date/time datatype is used to represent the columns using the date and
time values.

5. Geometric data types
The geometric data types represent two-dimensional data objects. Moreover, these
data types help to perform various operation like rotation, scaling and translation
etc.
Network Address type
Today we do have many network address types like IPV4, IP V6, and MAC address.
Moreover, this PostgreSQL offers different data types to store in this address.

6. It can store in a network address, instead of plain text, it is preferable to keep these
data types.
Enumerated data types
In PostgreSQL, enumerated data types are useful for representing the rarely
changing information such as country code (or) branch id. So to ensure data
integrity, the enumerated data type is defined with a table with a foreign key.
Range type
These represent data that uses the data range. These range types can be a discrete
range (or) continuous ranges.

7. Pseudo types
PostgreSQL contains several special-purpose entries that are collectively called as
pseudotypes. Moreover, a pseudo data type cannot be used as a column data type that
can be used as a column data type. Additionally, this can be used to declare a
function argument (or) a result type.
