             Summary: Improve error message when a table with columns of unsupported types is defined in pgsql
                 Key: TAJO-1949
                 URL: https://issues.apache.org/jira/browse/TAJO-1949
             Project: Tajo
          Issue Type: Task
          Components: JDBC Storage
            Reporter: Jihoon Son


When a JDBC-based table contains columns of unsupported types, that unsupported type is printed as number instead of its name as follows.

* pgsql
{noformat}
postgres=# \d test
    Table "public.test"
 Column | Type | Modifiers 
--------+------+-----------
 id     | real | 
{noformat}

* tajo
{noformat}
pgsql_db> \d test
ERROR: internal error: unsupported data type: '7'
{noformat}
