Possibly stopping at the tablespace level might be more straightforward. 
To avoid messing up the pages in shared buffers we'd perhaps need 
something like several shared buffer pools - each with either its own 
blocksize or associated with a (set of) tablespace(s).

Obviously this sort of thing has a pretty big architecture/code impact, 
probably better to consider a 1st iteration with it being initdb 
specifiable only (as that would still be very convenient)!
