We cannot use TOAST as is for BLOB/CLOB storage with a binary
IO interface over fastpath.
The reason is that you cannot force a column to be moved off
anyway and that the toast reference contains the original
objects size. Thus, opening a BLOB for writing would require
the reference in the main tuple to get updated and maybe
moving off the data first.
My plans for 7.2 are to use the toast table for storage, but
to build new data types with support hooks in the toaster for
it.
