Actually they seem to be two _different_ problems - 

1) we may need bigger tuples for several reasons (I would also suggest 
making index tuples twice as long as data tuples to escape the problem 
of indexing text fields above 4K (2K?)

2) the LOB support should be advanced to a state where one could reasonably 
use them for storing more than a few LOBs without making everything else to 
crawl, even on filesystems that don't use indexes on filenames (like ext2)

After achieving 2) support could be added for on-demand migrating of LONG 
types to LOBs

I guess that Jans suggestion is just a quick hack for avoiding fixing LOBs.
