The idea is that PG is shipped with a default representing the best of our knowledge and users are not encouraged to change it. When a user sends a "PG does not use my index" or "Why doesn't it scan sequentially?" message to one of the support lists, we advise her/him to set index_cost_algorithm to 3 (or whatever we feel appropriate) and watch the feedback we get. We don't risk anything, if the default is the current behaviour.
