Thanks, Steve, but I'm not feeling very cheery now.. 1) The sl_log_1 table has xid's in the range of 260914376 or so… Now the master node is staying on 8.3 for the moment; so I guess we're ok until we move it over.. but then what? what are the implications if the sl_log_1 table has transactions with lower xids in it? can we avoid problems if we make sure all nodes are up to date before the migration of the master node (and hence sl_log_1 is empty?)
2) How do I get the 8.4 version of the slony stored functions installed on the node that's moving up from 8.3 to 9.0? Once I pg_upgrade the box, and recompile and install slony for 9.0, will an update_functions suffice?
