Centralize PostgreSQL page header data structures.
These data structures were copied a few places (but only once in the core code) so put them in a place where everyone can use them. To do this create a new file, static.auto.h, to contain data types and macros that have stayed the same through all the versions of PostgreSQL that we support. This allows us to have single, non-versioned set of headers and code for stable data structures like page headers. Migrate a few types from version.auto.h that are required for page header structures and pull the remaining types from PostgreSQL directly. We had previously renamed xlog to wal so update those where required since we won't be modifying the PostgreSQL names anymore.

PostgreSQL Types That Do Not Vary By Version

|
||||
Despite the .auto.h suffix this file is not automatically generated, though it could be. We use this suffix to emphasize that the
|
||||
types have been copied from PostgreSQL and to exclude this file from project code counts.
|
||||
|
||||
For each supported release of PostgreSQL check the types in this file to see if they have changed. The easiest way to do this is to
|
||||
copy and paste in place and check git to see if there are any diffs. Tabs should be copied as is to make this process easy even
|
||||
though the pgBackRest project does not use tabs elsewhere.
|
||||
|
||||
Comments should be copied with the types they apply to, even if the comment has not changed. This does get repetitive, but has no
|
||||
runtime cost and makes the rules a bit easier to follow.
|
||||
|
||||
If a comment is changed then the newer comment should be copied. If the *type* has changed then it must be moved to version.auto.c
|
||||

|

* lets us pretend that pre-7.3 databases have page version number zero.
|

* We constrain page sizes to be multiples of 256, leaving the low eight
|
||||
* bits available for a version number.
|
||||
*
|
||||
* Minimum possible page size is perhaps 64B to fit page header, opaque space
|
||||
* and a minimal tuple; of course, in reality you want it much bigger, so
