Rails core - Oct 2012 - Rails 3.2/4 force prepared statements to be used

I''ve already asked this on StackOverflow with no luck on answer - 
http://stackoverflow.com/questions/12617237/rails-3-2-force-prepared-statements

Simplified case:

Hotel.find(1) - executes using prepared statement
SELECT "hotels".* FROM "hotels" WHERE
"hotels"."id" = $1 LIMIT 1 [["id", 1]]

Hotel.where(id: 1) - no prepared statement
SELECT "hotels".* FROM "hotels" WHERE
"hotels"."id" = 1

t = Hotel.arel_table; Hotel.where(t[:id].eq(1)) - no prepared statement
SELECT "hotels".* FROM "hotels" WHERE
"hotels"."id" = 1

Hotel.where(''id = :id'', id: 1) - no prepared statement
SELECT "hotels".* FROM "hotels" WHERE (id = 1)

So question, how to force rails to use prepared statements? May be not in 
all cases, but at least with arel_table
