When subscribing, I got the following error on the receiver slon:

declare LOG cursor for select
   log_origin,
   from "_test".sl_log_1 where log_origin = 1 and ( order by log_actionseq;

Apparently, in sync_helper.c (remote_worker.c line 4626) there_s 
unexpected data in provider->helper_qualification.
This happens with CVS HEAD.
Any hints?

Andreas
