Robert Haas 01b02c0eca pg_plan_advice: Avoid a crash under GEQO. 
The previous code could allocate pgpa_sj_unique_rel objects in a context
that had too short a lifespan. Fix by allocating them (and any
associated List-related allocations) in the same context as the
pgpa_planner_state to which they are attached. We also need to copy
uniquerel->relids, because the associated RelOptInfo may also be
allocated within a short-lived context.
