Comment(by strk):

 Today I tweaked the function to protect against specifying a factor < 2
 and to recommend creating an index on the source table if missing (it's
 really only needed if the source table has many tiles).

 I was wondering if the function should also create a spatial index on the
 overview table, or do we leave that to the caller to decide upon ? Or we
 accept flags to determine that ?

 Also, should the created overview table inherit permissions of the parent
 ?
