The isbn_issn data type was included in PostgreSQL 8.1 and earlier,
and did not handle UPCs or EANs. PostgreSQL 8.2 has replaced the
isbn_issn contrib project with the new isn contrib project, which
handles ISBNs, ISSN, UPCs, EANs, and lots of other good stuff. If you
need to manage bar codes in your project, this is the data type for you!
