These text files duplicated the main HTML and PDF documentation

formats. The trouble involved in maintaining them greatly outweighs

the likely audience for plain-text format. Distribution tarballs

|
will still contain files by these names, but they'll just be stubs
|
||||||
|
directing the reader to consult the main documentation.
|

The plain-text <filename>INSTALL</> file will still be maintained, as
|
||||||
|
there is arguably a use-case for that.

Fix possible mis-replay of WAL records when some segments of a

The WAL update could be applied to the wrong page, potentially many
|
||||||
|
pages past where it should have been. Aside from corrupting data,
|
||||||
|
this error has been observed to result in significant <quote>bloat</>
|
||||||
|
of standby servers compared to their masters, due to updates being
|
||||||
|
applied far beyond where the end-of-file should have been. This
|
||||||
|
failure mode does not appear to be a significant risk during crash
|
||||||
|
recovery, only when initially synchronizing a standby created from a
|
||||||
|
base backup taken from a quickly-changing master.

In some cases WAL replay would mistakenly conclude that the database

Fix possible mis-replay of WAL records when some segments of a

The WAL update could be applied to the wrong page, potentially many
|
||||||
|
pages past where it should have been. Aside from corrupting data,
|
||||||
|
this error has been observed to result in significant <quote>bloat</>
|
||||||
|
of standby servers compared to their masters, due to updates being
|
||||||
|
applied far beyond where the end-of-file should have been. This
|
||||||
|
failure mode does not appear to be a significant risk during crash
|
||||||
|
recovery, only when initially synchronizing a standby created from a
|
||||||
|
base backup taken from a quickly-changing master.

In some cases WAL replay would mistakenly conclude that the database

hot-standby queries before the database was really consistent. Other

These text files duplicated the main HTML and PDF documentation

formats. The trouble involved in maintaining them greatly outweighs

the likely audience for plain-text format. Distribution tarballs

|
will still contain files by these names, but they'll just be stubs
|
||||||
|
directing the reader to consult the main documentation.
|

The plain-text <filename>INSTALL</> file will still be maintained, as
|
||||||
|
there is arguably a use-case for that.
