[COMMITTERS] pgsql: Fix possible crash with Parallel Bitmap Heap Scan. - Mailing list pgsql-committers

Fix possible crash with Parallel Bitmap Heap Scan.

If a Parallel Bitmap Heap scan's chain of leftmost descendents

would mistakenly create a non-shared TIDBitmap and then try to perform
shared iteration.

Report by Tomas Vondra.  Patch by Dilip Kumar.
