* bufmask.h
|
|
* 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.
