Re: Logging the feature of SQL-level read/write commits

Hello,

may be you can find more informations regarding WAL concepts in
Write Ahead Logging — WAL
http://www.interdb.jp/pg/pgsql09.html

It  seems very complicated to change WAL format ...

Maybe there are other solutions to answer your need,
I found many interesting solutions in postgres archives searching
with words "flashback", "timetravel", "tablelog", ...

My prefered is "AS OF queries"
https://www.postgresql.org/message-id/flat/78aadf6b-86d4-21b9-9c2a-51f1efb8a499%40postgrespro.ru

and more specificaly syntax
VERSIONS BETWEEN SYSTEM TIME ... AND ...
that would permit to get history of modifications for some rows
and help fixing current data
