Yes. > allow index-only scans to skip "Heap Fetches" in more cases. Uh, by definition an index-only scan only scans the index, not the heap, right? It is true there are fewer heap fetches, but fewer heap features I thought mean more index-only scans. -- Bruce Momjian <br...@momjian.us> https://momjian.us EnterpriseDB https://enterprisedb.com + As you are, so once was I.
