Initial Comment:
I have created a table on a 32bits system having a boolean colum consisting of
268435456 true values and one false value.
create table test2 (mytest boolean);
Then I executed the following query:
select * from test2 where mytest = false;
This resulted in:
Program received signal SIGSEGV, Segmentation fault.
