This is unrelated to the change in the with/without time zone default;
it happens because we have tightened up the rules for implicit casting.

This is also unrelated. There is no scenario in which a parse error
will lead to signal 9. I would guess that you have one of the versions
of Linux in which the kernel will issue kill -9's against
randomly-selected user processes anytime it starts feeling low on
memory. Buying more RAM or increasing swap space is the best answer
AFAIK.
