Don't worry - it can hold a very large number of records and it will not
overlap. That key represents actually the position in the hash table. It
does not have a fixed length, it will get as long as it is needed. The
first int represents the dimension of the hash table ( default is 1024,
but you can increase by setting hash_size module parameter - beware that
you have to put there the power of 2). The second int is the position in
the list for that hash_index.
