What happened

PostgresqlColumnConverter#createExternalConverter

case FLOAT:
return (val, index, statement) ->
statement.setFloat(index, ((ColumnRowData) val).getField(index).asFloat());

((ColumnRowData) val).getField(index).asFloat() 等于null时 ，调用 setFloat(int fieldIndex, float x) 会发生异常，因为 Float 等于null时不能转为float

What you expected to happen
