How big an integer in SQLite?

I am used to using a bigint type in postgres in some cases for table 
creation. I assume sqlite doesn't care how big the integer gets for an 
id. Is this true?

In postgres:

create sequence oid_seq;

create table test (
   oid        bigint not null primary key,
   tid        bigint not null
);


In sqlite I am doing this to emulate - since bigint is meaningless in 
sqlite and because it will get an auto incremented primary key:

create table test (
   oid        integer not null primary key,
   tid        integer not null
);
