-------------------------------------------------
[~giacomotaylor]
To do this I may need to read how the multi tenant tables are stored in the
SYSTEM table and how the base multi-tenant table is accessed and how the
tenant-specific tables are accessed.
> Only cache guideposts on physical PTable

> Rather than caching the guideposts on all tenant-specific tables, we should
> cache them only on the physical table. On the client side, we should also
> update the cache with the latest for the base multi-tenant table when we
> update the cache for a tenant-specific table. Then when we lookup the
> guideposts, we should ensure that we're getting them from the physical table.
> Otherwise, it'll be difficult to keep the guideposts cached on the PTable in
> sync across all tenant-specific tables (not to mention using quite a bit of
> memory).
