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