Bug reference: 2802
Logged by: Albert Strasheim
Email address: fullung@gmail.com
PostgreSQL version: 8.1
Operating system: Windows
Description: Feature request: tinyint and unsigned types
Details:
MySQL's support for 1-byte integers and unsigned types are very useful in
some applications where it makes sense to express certain values as 1-byte
values or as unsigned values. Having support for this in PostgreSQL would be
awesome.
Yes, bigger types can be used, but they introduce additional storage
requirements that maybe be excessive in certain situations.
