I think the closest thing you'd find to that is jsonb, or contrib/hstore if you'd like something with a bit less complexity. The notation is unlikely to look much like Oracle, but they both have the ability to store sets of key/value pairs. https://www.postgresql.org/docs/current/datatype-json.html https://www.postgresql.org/docs/current/hstore.html regards, tom lane
