From f35742ccb7aa53ee3ed8416bbb378b0c3eeb6bb9 Mon Sep 17 00:00:00 2001 From: Robert Haas Date: Wed, 8 Mar 2017 12:05:43 -0500 Subject: Support parallel bitmap heap scans. The index is scanned by a single process, but then all cooperating processes can iterate jointly over the resulting set of heap blocks. In the future, we might also want to support using a parallel bitmap index scan to set up for a parallel bitmap heap scan, but that's a job for another day. Dilip Kumar, with some corrections and cosmetic changes by me. The larger patch set of which this is a part has been reviewed and tested by (at least) Andres Freund, Amit Khandekar, Tushar Ahuja, Rafia Sabih, Haribabu Kommi, Thomas Munro, and me.
