Is there a data type smaller than smallint (16bit)? I need a column with only numbers from 1 to 31 so i think that 5bits are enough and I do not want to waste space with the overhead of 11bit per tuple.

In docs there is no such 1 byte integer so I think the best way is to use small int. If you don’t consider to do any math operations you can also use just varchar(2) (but this is not the best idea).
