Greetings: I occasionally find the need to perform some maintenance on one or more of thirteen different databases. Typically, due to the interaction between the databases, I need to lock down the databases for a short period of time so that no updates are being performed anywhere. I do not want to shut down the postmasters as it is a clustered environment and would rather just leave that alone. Also, since this is a 24 hour shop, it would be good if people could still query, but not change any data. All this work is done at times like 03:00 in the morning and the number of people working at that time is limited to five or six. Is there some easy way of doing this without having people log out of the application?
