Write a script that does "something" that results in 16MB of WAL logging and 
run it whenever you want a rotation to occur. Inserting a few hundred 
thousand rows into an otherwise empty table should work. If it's not 
indexed it won't impact your server much, especially if your normal 
transaction volume is that low.
