what data type to store fixed size integer?

[Arash pajoohande <apajoohande@xxxxxxxxx>]

hi there
I wan to store a 10 digits integer in a column of table.
the data type does not need any arithmetic aperations (as of integers).
maybe its good to use bigint, but it is Postgres specific and is not part of SQL standards
what is the best data type (fastest) to store it? any help would be appreciated.

thanks in advance
