[Bucardo-general] any way to sync two master without purge one?

[Yan Chunlu]

I understand there was three sync type, "pushdelta", "fullcopy" and
"swap" in bucardo 4.

when doing master-master rep,  fullcopy is the first step, and swap is the next.

even in bucardo 5, I guess there is always the needs that start sync
without empty one of them.  another project called "rubyrep" which
support this way, but it compare the records one by one which cause it
is very slow while network quality is bad.

is there any change that bucardo could have this feature? to start
sync two master database without clear one of them first?  thanks!
