Research direction
Start with the linked DuckDB interval testcase and compare how the JDBC driver currently exposes interval fields with the existing DuckDBUserArray, DuckDBMap, and DuckDBUserStruct classes. Done means interval columns return a distinguishable custom type instead of String, allowing integrations to convert the value to their preferred duration representation.

Description
Description
DuckDB supports interval types, but the DuckDB JDBC Driver returns these fields as String. In comparison the PostgreSQL JDBC Driver returns a custom org.postgresql.util.PGInterval instance.
Expectation
This makes the integrations for the DuckDB JDBC Driver problematic in certain situations. I would expect a custom class to be returned similar to the org.duckdb.user.DuckDBUserArray, org.duckdb.user.DuckDBMap, or org.duckdb.user.DuckDBUserStruct classes.
Even if this new class behaves the same as a String instance, using a different class would make it possible for the implementations to convert that to a proper Duration type at the end, or whatever the end-user prefers.
