It's quite straight forward - and works well for the most primitive data types. Loading seems not to be the issue - the conversion from postgres to works fine - but on Update - the exceptions are thrown. "time with time zone" or xml either a Missing Operator- (xml = text) or an Invalid Cast-Exception occurs. Here the example code, To reproduce the issue - just setup a database with a table - first add only primitive data-type rows (int , uid, string, text ect.) test it - and you'll see - update just works fine.

If we set the batch size to 10 then Row Updating will be raised for 100 times where as Row Updated will be raised only for 10 times.

There are also two events associated with this that you can use � Row Updating and Row Updated. in the absence of batch update, both of these events are raised for each and every row being updated.

For example, if we are updating 100 rows, both of these rows are raised for 100 times.

Then we set the Updated Data Source property of the Sql Command property to enumerated value of Update Row Source. The Updated Row Source property can control how the values returned from the data source are mapped back to the Data Set.

Setting this property to a value of None is necessary when using batch update feature of Data Adapter.

Then add any extended data-type, like a time value, xml etc - and the update throws the exceptions @digital-void, please check the minimal testcase in my commit above. Update(Data Row[] data Rows, Data Table Mapping table Mapping) at System.

Specifying a json or xml field as part of the table indeed triggers an error, but it's a backend 42804 error because npgsql sends values as text. However, it doesn't look like what you got, and moreover I can see no issue when inserting timestamps (with timezone or otherwise). Sorry that it took some time to write back - my internet connection was (is) down - I've got to work via mobile...

Please look at my testcase and try to see if there's any real difference with your code. So - for the exception call stack - it only has external code - maybe I need to include the npgsql source for more information on this.
