Working with Dates ​

SQL Server has functions for modifying a date, such as DATEADD(…)

Postgres has an interval type which allows you to add/remove in a much more semantic manner.

For example, in SQL Server to add 5 days to the current date we might do:

SELECT DATEADD(day, 5, getutcdate())

In Postgres we would achieve the same like so:

SELECT now() + ‘5 days’::interval;
