Hi, I attached a patch to output the LSN before execution to the server log
when executing a specific command and accidentally erasing data.
A detailed background has been presented before.
In short explain: After the DBA's operation failure and erases the data, it is
necessary to perform PITR immediately.
Since it is not possible to easily obtain information for doing the current
PITR, I would like to solve it.
The specification has changed from the first proposal.
-Target command
DROP TABLE
TRUNCATE
-Setting file
postgresql.conf
log_recovery_points = on #default value is 'off'. When the switch is turned
on, LSN is output to the server log when DROP TABLE, TRUNCATE is executed.
-How to use
1) When executing the above command, identify the command and recovery point
that matches the resource indicating the operation failure from the server log.
ex) LOG: recovery_point_lsn: 0/201BB70
STATEMENT: drop table test ;
2) Implement PostgreSQL document '25 .3.4.Recovering Using a Continuous
Archive Backup.'
*Set "recovery_target_lsn = 'recovery_point_lsn'" at recovery.conf.
Although there was pointed out that the source becomes complicated in the past,
we could add the function by adding about 20 steps.
What do you think about it? Do you think is it useful?
