Currently, we only need this logic in order to cost a Bitmap Heap Scan. But a pending patch for Parallel Bitmap Heap Scan also uses it to help figure out how many workers to use for the scan, which has to be determined prior to costing. So, move the logic to a separate function to make that easier. Dilip Kumar. The patch series of which this is a part has been reviewed by Andres Freund, Amit Khendekar, Tushar Ahuja, Rafia Sabih, Haribabu Kommi, and me; it is not clear from the email discussion which of those people have looked specifically at this part.
