The planner (optimizer) estimates costs of each possible execution plans for a SQL statement, then executes the plan with the lowest cost. The planner does its best to select the best execution plan, but it is far from perfect, since it may not count some data properties, like correlation between columns. . pg_hint_plan makes it possible to tweak PostgreSQL execution plans using so-called "hints" in SQL comments, like /*+ SeqScan(a) */.
