Fwd: Re: [INTERFACES] psql ERROR : Character Types Tuple is too big: size xxxxx

Thanks Tom,
Taking the choice of 'text' fields ; "no needs of blank-padding in every
record..."
BUT why psql does not raise an error in 'create table' ?
Maybe documentation needs more informations on this ? (In Data types)
Emmanuel.

Well, actually, we are more interested in getting rid of the limitation
than in adding more code that depends on it... there may even be a fix
in 7.0...

I found this in the hackers mailing list archive:

Bruce Momjian <pgman(at)candle(dot)pha(dot)pa(dot)us> at Technische
Universitaet Muenchen, Germany

Can I ask how our big open items for 7.0 are doing:

Long tuples/TOAST(Jan)
Foriegn keys/action buffer(Jan)
Unify date/time types(Thomas)
Outer Joins(Thomas)

I am only asking to know if we should continue with the planned Feb 1
beta?

====================END CLIP.

The problem is that none of the followups mentioned long tuples, so that
might have slipped through the cracks.
