Dave,

My thoughts as well. If we encounter an 'unknown' type, just return it
as a String. Do you have time to fix this?

As a work around using an explicit cast should also work: select
container_20_ft_qty AS QTY_OH, 'Container'::text AS NOMENCLATURE
from ue_summary_mtmc where uic = 'WAQJAA'

thanks,
--Barry
