Nor would I, but one possibility that comes to mind is adding the  
ability to determine the sequence of transaction commits. Currently,  
Slony has no choice but to skip from one consistent state to the  
next, and for at least some of that it also has to know what XIDs  
were uncommitted in a batch. I have to wonder if there's a better way.

Though, the counter-argument is that batching greatly reduces the  
load on the slaves...

Something else I've noticed is that slaves pulling data from a master  
present a non-trivial load (seeming much larger than the triggers  
that log the data), so perhaps there is something to be had there as  
well.
