That's a question for the pgAdmin guys, but I know that PostgreSQL has a type called 'set', which is nothing to do
withsets as you understand
them.

Look up CHECK constraints.
Lack of 'MySQL sets' in Postgres is NOT an oversight. It's a random,
non-SQL standard type that the MySQL developers made up one day that no
other database on Earth supports. Why should Postgres support it? It's
just a lame workaround for MySQL not supporting constraints.
(Sorry to sound all worked up about it, but it's one of the things I
find annoying about MySQL...)
