> Key: AIRFLOW-3488
> URL: https://issues.apache.org/jira/browse/AIRFLOW-3488
> Project: Apache Airflow
> Issue Type: Bug
> Components: contrib, gcp, operators
> Affects Versions: 1.10.1
> Reporter: Duan Shiqiang
> Priority: Major
>
> PostgresToGoogleCloudStorageOperator generates bigquery schema wrongly for postgres data type ARRAY (it generates bigquery schema with that filed as string).
> The generated bigquery schema set mode for one field to 'REPEATED' if the type_code of the postgres column is one of (1009, 1005, 1007, 1016). see: [https://github.com/apache/incubator-airflow/blob/master/airflow/contrib/operators/postgres_to_gcs_operator.py#L185] . This doesn't include all possible array types (see [https://github.com/psycopg/psycopg2/blob/master/psycopg/typecast_builtins.c)]
