What is the difference between timestamp and datetime in Postgres?

In PostgreSQL, both timestamp and datetime are data types for storing date and time values. However, there are some differences between them.

The timestamp data type is used for storing both date and time values. It is generally more flexible than the datetime data type, as it allows you to store fractional seconds. The timestamp data type is also timezone-aware, which means you can store and manipulate dates and times in different time zones. In Postgres, the timestamp data type has a precision of up to six decimal places.

The datetime data type, on the other hand, only stores date and time values up to the second. It is not timezone-aware, so you cannot store dates and times in different time zones. Additionally, the datetime data type has been deprecated in PostgreSQL, and it is recommended that you use the timestamp data type instead.
