Unless you have somehow gotten PostgreSQL running on an IBM 7070, the
range 0-4 can be represented by three binary digits, aka booleans. :-)
The only booleans I know of are 0 and 1. ;-)
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.
No it is not a lot of them.
So then "smallint" is the best bet, right?
Thank you
2. If there are a lot of them, it's worth encoding them into a
bitstring.
Hi!
If you really need 1-byte integer, you can use "char" type. Cast it
to/from int.
