What do you exactly mean? Do you care about storage requirements or constraints? The smallest numeric type in postgres is smallint: range is +/- 32K and you need two bytes. You can use check constraint to restrict the range (postgres doesn't have signed / unsigned types):
create table T ( tint_signed smallint check ( tint_signed >= -128 and tint_signed =< 127 ), tint_unsigned smallint check ( tint_unsigned >= 0 and tint_unsigned =< 255 ) )
Yes. Considering the storage requirements , I am looking for TINYINT kind of data type.
if you care about storage then "char" (yes, with quotes) might be the right type for you.
