create_table :Room do |t|
  t.daterange :availability
end

Room.create(availability: (Date.today..Float::INFINITY))
Room.first.availability # => Wed, 19 Sep 2012..Infinity

connection.execute(%q{
    alter table events
    alter column "when"
    type tsrange using tsrange(lower("when"), upper("when"))
})

Nice, thanks
