Agreed.  The thread referenced above never really answered why a configure time
option would be needed.

+       uint32          slru_pages_per_segment; /* size of each SLRU segment */

Should this be expanded ever so slightly?  A new reader of the code might
wonder about the relationship between "pages_per" and "size".

No objections (apart from the catversion =)) from reading the patch.
