Well.. What is the interval in mysql? Is that supposed to represent +
interval '1970 years' + interval '1 month' + interval '2 days'?

In PG you probably have a few options. One, store it as a date, and use
dateAdd() functions. Two, store it as text and set the value's to
things like '1 hour', '2 years', '70 years 1 month 2 days 4 hours 20
minutes', etc

The calc like 'select someDate + interval yourNewField'

Of course... I have not actually tried any of this :-)
