I'm wondering if it would be possible to add the idea of 'administrative command'. My understanding is that very few things require superuser access, so it might be possible to put more stringent requirements on their use. It's much more likely that these commands do not need to run without human intervention, so (for example), it might be far more practical for these commands to require the user to supply a password to gain access to the SU account on all the nodes; or perhaps the commands are run from a secured workstation that has the proper credentials in ~/.pgpass. I realize that the requirement for these commands to happen as part of the replication stream (in the correct order with everything else) complicates this, but it should be possible to allow for a SU-enabled slon process to connect to remote machines via an SU account to process those admin commands and then be shut-down again after they were finished. -- Jim C.
