Sure, pick the one which requires new syntax!  ;-)
 
How about two new ALTER TABLE actions:
 
   ALTER [ COLUMN ] column SET COMPRESSION_THRESHOLD integer
   ALTER [ COLUMN ] column SET EXTERNAL_THRESHOLD integer
 
Or can you suggest something better?
 
Laurent, would something like this address your needs?  I was assuming
that if the point is to reduce I/O, you were interested in doing more
compression, not in storing more values out-of-line (in the separate
TOAST table)?  Would it be manageable to tune this on a column-by-
column basis?
