Please enter a FULL description of your problem:

Attempting to delete from a table by inet, with rows containing NULL inet
types results in a backend crash

Please describe a way to repeat the problem.   Please try to provide a
concise reproducible example, if at all possible: 

create table blah ( ip_address inet );

insert into blah values('');
INSERT 18761 1

delete from blah where ip_address = '';

insert into blah values(NULL);
INSERT 18762 1

delete from blah where ip_address = '';
pqReadData() -- backend closed the channel unexpectedly.
        This probably means the backend terminated abnormally
        before or while processing the request.
We have lost the connection to the backend, so further processing is impossible.  Terminating.
