Tom Lane 3b167a4099 If a LIMIT is applied to a UNION ALL query, plan each UNION arm as ... if the limit were directly applied to it. This does not actually add a LIMIT plan node to the generated subqueries --- that would be useless overhead --- but it does cause the planner to prefer fast- start plans when the limit is small. After an idea from Phil Endecott.		21 years ago
