Of course a first mail after a release must have the earned praise:
Very nicely done, I like it all ;-)

Reading the TODO, I see 'Allow text, char(), and varchar() overhead to be
only 2 bytes, not 4 bytes'
While this is very good for char and varchar, text is not a candidate
since it is usually a blob datatype, without a length restriction (or a 2Gig

I think it should alternately read:
Allow varchar() overhead to be only 2 bytes
remove char() 4 byte overhead, use atttypmod instead
make text a blob datatype (maybe storing <= 8k row with tuple, >=8k in blob

What do you think ?
