20,000 Postgres Timestamp Format Examples

You will love this blog because date, timestamp functions and formatting differ dramatically between databases, and Postgres handles them uniquely, but I have covered everything you need to know about formatting with brilliant examples and clear and concise explanations.

All of these examples have come from my books and training classes. Please do me a favor and tell your training coordinator that you know the best technical trainer in the world. Ask them to hire me to train at your company, either on-site or with a virtual class. They can see our classes, outlines, and a sample of my teaching at this link on our website.

I bet you didn’t know you could use the TO_CHAR function in the WHERE and AND clauses to filter rows. The query below only returns rows where the customer_timestamp has a month of December, a day of Saturday, a minute of 54, and a second of 35.
