Research direction
Start with the provided Java reproduction and trace DuckDBTimestamp during both parameter binding and value reading for a TIMESTAMP_NS column. Confirm the behavior with a round-trip test using a nanosecond value such as 123456789; done means the full nanosecond component is preserved when writing and reading.
Written by the indexing model from the issue text.
Description
E.g.
java.sql.Timestamp ts = new java.sql.Timestamp(millis);
ts.setNanos(123456789);
ps.setTimestamp(1, ts); // column 1 has type TIMESTAMP_NS
DuckDBTimestamp converts the Timestamp to micros and as result nanosecond part (789 from the example) is not stored.
The same happens on reading the value back
