Hello all

I'm in the need for my custom written replication engine to obtain the current 
transaction id from a trigger function. As far as I'm told it's not possible 
today. Would people object much if this functionality was added for 8.2 ? 
It's the last piece of postgresql C code I have left in my application and I 
think it would be a nice information in general to have available for users. 
If not for anything else then for simple statistics.

I attached the function I use with great success today.

Best regards,
Nicolai Petri


Datum get_transaction_id(PG_FUNCTION_ARGS) {
        TransactionId curxact;

        return Int32GetDatum(curxact);
