## Limitations
- Does not support schemas with [field types](https://duckdb.org/docs/sql/data_types): nested arrays/lists, UTF8/string arrays/lists, structs or map fields. For example:
- Supported:
- `SELECT [1, 2, 3];`
- `SELECT ['1992-09-20 11:30:00.123456789', 'epoch'::TIMESTAMP]
- Unsupported:
- `SELECT [['duck', 'goose', 'heron'], ['frog', 'toad']]`
- `SELECT {'x': 1, 'y': 2, 'z': 3}`
- `SELECT MAP(['key1', 'key2', 'key3'], [10, 20, 30])`
- `SELECT ['duck', 'goose', 'heron'];`
