Modify optimizer data structures so that IndexOptInfo lists built for
create_index_paths are not immediately discarded, but are available for
subsequent planner work.  This allows avoiding redundant syscache lookups
in several places.  Change interface to operator selectivity estimation
procedures to allow faster and more flexible estimation.
Initdb forced due to change of pg_proc entries for selectivity functions!
