Full test case, reproduced in 8.4.2 on two different hosts
create table test (id serial primary key, t1 text, t2 text);
create function myhash(test) returns text as 'select md5($1::text)' language sql immutable;
create index myhash on test( myhash(test) );
alter table test add t3 text;
alter table test drop t3;
insert into test(t1,t2) select 'foo', 'bar';
PS. I realise that marking of CAST (rowtype as text) as immutable may be not safe.
But this behaviour is probably a bug anyway.
