Nodes like Memoize report the cache stats for each parallel worker, so it makes sense to show the exact and lossy pages in Parallel Bitmap Heap Scan in a similar way. Likewise, Sort shows the method and memory used for each worker. There was some discussion on whether the leader stats should include the totals for each parallel worker or not. I did some analysis on this to see what other parallel node types do and it seems only Parallel Hash does anything like this. All the rest, per what's supported by ExecParallelRetrieveInstrumentation() are consistent with each other.
