Unless you have somehow gotten PostgreSQL running on an IBM 7070, the range 0-4 can be represented by three binary digits, aka booleans. :-)

To be serious, though, the situation is:

1. If there are just one or two tinyints, having a tinyint type wouldn't save any space in the row.
2. If there are a lot of them, it's worth encoding them into a bitstring.
