Hello, We see that UUID field in Postgres returns null when queried from Drill. This happens as JdbcRecordReader#JDBC_TYPE_MAPPINGS does not map java.sql.Types.OTHER to any MinorType. Postgres UUID type is mapped to java.sql.Types.OTHER.
A fix would be to read the value as an object and then convert it to a string. If we read the values as string what happens to the other types mapped to Type.OTHER? Thank you, Priyanka Bhoir
