Possibly we could allow '.' as long as we forbade /, but the other
trouble with allowing . is that it encourages people to try to specify
the filetype suffix (as indeed Oleg was doing). I'd prefer to keep the
suffixes out of the SQL object definitions, with an eye to possibly
someday migrating all the configuration data inside the database.
There's a reasonable argument for restricting the names used for these
things in the SQL definitions to be valid SQL identifiers, so that that
will work nicely...
