These columns can be with or without time zone information. While working on a large database project, often we come across multiple columns that store data in timestamp format. Using the CAST function in PostgreSQL to convert timestamps to other formats Using the INTERVAL function in PostgreSQL In this article, we are going to focus on the following concepts.Įxtract date parts from existing timestamps Also, we can calculate time intervals using these functions that will help us analyze what has changed between those two timeframes.

PostgreSQL is one of the leading open-source relational database systems that can be used to build operational databases as well as data warehouses. In this article, we are going to explore some of the important Date and Time functions that can be used in PostgreSQL and how they can be implemented henceforth. These KPIs help businesses understand and gauge their performance and also aids in making decisions necessary for their development.
