3 * bufmask.h
4 * Definitions for buffer masking routines, used to mask certain bits
5 * in a page which can be different when the WAL is generated
6 * and when the WAL is applied. This is really the job of each
7 * individual rmgr, but we make things easier by providing some
8 * common routines to handle cases which occur in multiple rmgrs.
