And yes, we can force them by some means or the other to just use one database with the correct name. But it would be nice, if we wouldn't have to. The work around with a custom 'createdb' command looks nice at first, but as one can use 'create database' as an SQL command, it does not really help out. So currently, I think I will leave it with 'sameuser' or similar, and let the students know about the database name. Unfortunately, the pgAdmin III (version 1.4) likes to pop up a message for any database, the user does not have access to. So this will keep them a little busy on pgadmin3 startup, but anyway, they don't have to use this tool. I was initially thinking, there 'should' be some way to limit the access in the desired way. So now I know, there is not. Schemas might be a way out of the problem, but it's a little late now, to force them using different schemas and take care of access control themselves. Maybe next year.
