> As for now user is able to create external HAWQ table on top of Hive table with complex types(LIST, MAP, STRUCT, UNION) and those types are being serialized as TEXT.
> But if user uses HCatalog integration feature and queries Hive tables having compex type columns through HAWQ he/she gets error.
> The goal is to serialize complex types to text when using HCatalog integration.
> Changes required:
> - PXF:
>  -- add sourceType field to getMetadata endpoint.
> - HAWQ:
>  -- master:
>  --- update stored procedure pxf_get_item_fields, add sourceType field to responce.
>  -- psql: 
> --- update describe logic for Hive tables to show sourceType column in \d(\d+)
