Hypertables definitely had the arrays columns auto-expanding with the custom node type. Not sure what else it would look like for what you describe.

That said, don't sleep on the "this is awesome" parts in this project... my personal favorite is the automatic schema detection:

``` CREATE TABLE my_iceberg_table () USING iceberg WITH (definition_from = 's3://bucket/source_data.parquet'); ```
