hi,
basically the question is simple: there is sl_status and it shows lag in
events.
i know that some events are "system" ones (like add table and so on),
but there is sync event which sends data.

what it really is? when slony creates new sync event? is it related to
modification statements? modification transactions? time intervals?

i would really like to understand, so if it is clearly defined/described
some place i would really love to get pointer to this place. or perhaps
a description in here, on the list.

best regards,

depesz
