Previously, the planner used a direct query via the SPI interface to retrieve metadata info needed for query planner functions like query rewriting. This commit updates the planner to use our caching system. This is a performance improvement for pretty much all operations, both data modifications and queries. For hypertables, this added a cache keyed by the main table OID and added negative entries (because the planner often needs to know if a table is /not/ a hypertable).
