Yeah. I think we probably have to do that in any case because we have
an assumption that datatype input routines are allowed to make use of
a snapshot (see comments in fastpath.c for instance). The fact that
no one's noticed this crash before suggests that none of the common ones
actually do, but I don't think we want to back off that assumption.
There's still a question of whether we want to alter the treatment of
record-type input to make the handling of embedded domains more uniform,
but that's something for the future.
