Here is what I'm doing:

begin;
intarray = select intfield from table1; (11480 entries right now)

for(i = 0; i < intarray.length; i++){
select some data for that int value
if (come condition){
add int to list;
}
}

chunks = split list into chunks; (to avoid an in() with too many things in it, max of 2000
per chunk)
for each chunk{
//this update causes the error
update table2 set status = newstatus where id in (chunk[0], chunk[1]...);
}
delete from table1;
end;
