That's easily reproducible, your test case is just missing the
tablespace creation to be complete:
set default_tablespace to '';
\! rm -rf /home/ioltas/Desktop/tbspace/*
create tablespace tblsp location '/home/ioltas/ioltas/tbspace/';
create table test(id int primary key, processid bigint not null ,
ruleid bigint not null );
create index on test (ruleid);
create index on test (processid);
set default_tablespace to tblsp;
alter table test alter processid type bigint, alter processid drop not null;
select * from test; -- boom

I am just digging into it, instinctively that would be something in
tablecmds.c..
