My recollection for the enum approach though was that it only actually

what int.

I can see a positive demerit - lack of portability. I use PostgresQL, but
would not use its enums because that would make the application non-
portable to Derby or H2.

Similarly, I do use sequences, which are fairly commonly implemented but
accept that would require a rewrite if my code needed to be ported to
MySQL, which only has auto-incrementing columns.
