Running the following against HEAD and REL8_3_6:
Same problem exists in 8.2 and 8.1 as well. The code in ruleutils.c is
similar in 8.0 as well, except that the Assertion isn't there.
create table foo (a varchar(500));
create view bar as select case foo.a when '1' then 'foo' else 'bar' end as
fa from foo;
\d bar
Causes as assertion in the backend:

LOG: server process (PID 28408) was terminated by signal 6: Aborted
Attached is a simple patch that appears to fix this problem, not sure if it
suffices in general.
Looks good to me, at least.
