And you'll find a first TOAST snapshot at
http://www.postgresql.org/~wieck
It's not ready for production, and it only toasts a yet user
defined CLOB data type (that's coming with the snapshot). But
it does a fair job on it so far.
Tell me a little more about your needs and especially the
time constraints of your project. I would like to have a
small number of users with a need for that stuff right now.
It shouldn't be mission critical data. But it's the best time
to tackle basic conceptual mistakes.
In return you probably get a patch to apply on the 7.0
release and already have anything you'd have to wait for
until 7.1 otherwise.
