Thank you very much for your willingness to adapt. :)

sendyou an email about that later today.
I don't recall seeing an email from you about this yet? My apologies if
I missed it. I have added Alexander Korotkov to the CC list as he was
also listed as a possible mentor for TOAST'ing in slices.
As it relates to TOAST'ing in slices, it would be good to think through
how we would represent and store the information about how a particular
object has been split up. Note that PostgreSQL is very extensible in
its type system and therefore we would need a way for new data types
which are added to the system to be able to define how data of that data
type is to be split and a way to store the information they need to
regarding such a split.
In particular, the PostGIS project adds multiple data types which are
variable in length and often end up TOAST'd because they are large
geospatial objects, anything we come up with for TOAST'ing in slices
will need to be something that the PostGIS project could leverage.

We are certainly very interested in having you continue on and work with
the PostgreSQL community moving forward, though we do need to be sure to
scope the project goals within the GSOC requirements.
Thanks!
