> If data page has 8 unused bytes or more, it will be stored in a free list. As 
> result, free lists mostly contain "free pages" that are actually useless: 
> pair of (boolean, boolean) takes approximately 50 bytes. I think, we'll 
> increase this constant to something like 40, memory will be used more 
> efficiently and WAL usage will decrease in result.
