[jira] [Created] (SPARK-28097) Map ByteType to SMALLINT when using JDBC with PostgreSQL

Seth Fitzsimmons created SPARK-28097:
----------------------------------------

             Summary: Map ByteType to SMALLINT when using JDBC with PostgreSQL
                 Key: SPARK-28097
                 URL: https://issues.apache.org/jira/browse/SPARK-28097
             Project: Spark
          Issue Type: Improvement
          Components: Input/Output
    Affects Versions: 2.4.3, 2.3.3
            Reporter: Seth Fitzsimmons


PostgreSQL doesn't have {{TINYINT}}, which would map directly, but {{SMALLINT}}s are sufficient for uni-directional translation (i.e. when writing).

This is equivalent to a user selecting {{'byteColumn.cast(ShortType)}}.
