several types are either unique to PostgreSQL, such as geometric paths, or have several possible formats, such as the date and time types. Some of the input and output functions are not invertible, i.e., the result of

Introduction to PostgreSQL timestamp PostgreSQL provides you with two temporal data types for handling timestamps: timestamp: a timestamp without a timezone one. timestamptz: timestamp with a timezone. The timestamp datatype allows you to store both date and time. However, it does not have...
Category - Date/Time Types Category - Boolean Type Category - Enumerated Type Unlike other types, Enumerated Types need to be created using CREATE TYPE command. This type is used to store a static, ordered set of values, for example compass directions,i.e. NORTH, SOUTH, EAST, and WEST or...

PostgreSQL provides several data types for the DateTime values, such as TIME, DATE, INTERVAL, TIMESTAMP, and TIMESTAMPTZ. These data types allow us to store the DateTime values in a database. The time data type stores time values in the database, the date data type stores the date values...
