This topic is discussed again and again with huge friend of mine and MySQL sectarian. :) And must confess I agree with him in this particular point of view.
For me it’s strange that such powerful database as PostgreSQL, which has a lot of drums and whistles inside, doesn’t support SET types. Especially when we have ENUM support now!
Of course one may say that this functionality can be implemented using Bit String Types. But where is the joy of power? Where is the crystal clarity of the SQL script? :)
What’s you opinion, postgresman?
