Yes. > I still cannot find enough use-cases to allow manipulating slots, though. The use case for single-user mode is quite limited in general, but most things work in single-user mode unless they are something that intrinsically can't. For example, parallel query cannot be used in single-user mode, because there is only one process. Replication cannot work, for the same reason. But manual slot operations can work, so I do not think it is good to arbitrarily prohibit them. We do not need a reason to specifically allow them; it is enough that there is no good reason for them to be blocked. -- Robert Haas EDB: http://www.enterprisedb.com
