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.
