Indeed. But as someone else already pointed out, a seqscan is the only
reasonable plan for an unqualified "SELECT whatever FROM table" query;
lack of stats wouldn't deter the planner from arriving at that
conclusion.
My guess is that the OP is failing to account for some client-side
inefficiency in absorbing a large query result.
