Is any information about trigger-name and src-table available at the protocol-level?

See this issue in the pgjdbc-ng driver's issue-list:

https://github.com/impossibl/pgjdbc-ng/issues/111#issuecomment-61635914

 

Is this information available at the protocol-level so the driver can craft meaningful exceptions containing this info (table name causing the trigger to fail, name of trigger etc.)?

 

Thanks.
