I'm not sure it is a general rule. ISTM that extensions can use tmp files, 
and we would have no control about what they would do there.

For the level, ISTM that the implementation should not make this 
assumption. If in practice there is just one level, then the function will 
not recurse deep, no problem.

For the column, I'm not sure that "isdir" is necessary.

You could put it implicitely in the file name by ending it with "/", 
and/or showing the directory contents is enough a hint that there is a 
directory?

Also, I'm not fully sure why ".*" files should be skipped, maybe it should 
be an option? Or the user can filter it with SQL if it does not want them?
