+## How to insert array data into PostgreSQL
+DataAPI have not support inserting array data with `SqlParameter` yet.
+But, @ormu5 give us this workaround to insert array data.
+```sql
+insert into cfg.attributes(id, type, attributes)
+values(:id, :type, cast(:attributes as text[]));
+```
+where the value for attributes parameter is a string properly formatted as Postgres array, e.g., `'{"Volume","Material"}'`.
+
+Thanks to @ormu5.
