Thanks, Ajin.  Please consider this concurrent_abort callback as well. 
I think it provides more flexibility for the output plugin and I would 
therefore prefer it over a solution that hides this.  It clearly makes 
all potential optimizations impossible, as it means the output plugin 
cannot distinguish between a proper PREAPRE and a bail-out PREPARE (that 
does not fully replicate the PREPARE as on the origin node, either, 
which I think is dangerous).

Regards

Markus
