Description: support for optimizer hints in PostgreSQL
PostgreSQL uses a cost-based optimizer that uses data statistics, not static
rules. 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) */.
