Update of /home/cvsd/slony1/slony1-engine/src/slon
In directory main:/tmp/cvs-serv3863/src/slon

Modified Files:
	remote_worker.c 
Log Message:
- When you run MOVE SET, this populates sl_setsync for the moved set
  even on nodes that are not subscribed.  If, subsequent to doing this, 
  you attempt a SUBSCRIBE SET for a formerly-unsubscribed node, the
  subscription will fail right at the end when the slon tries to insert a
  new value to sl_setsync.

  The fix: DELETE from sl_setsync immediately before the INSERT.  This
  will silently blow away any 'offending' sl_setsync row.

As observed by Afilias staff...
