[CPANEL-29288] Non-Public Schemas in PostgreSQL Databases Do Not Restore

plague
Hello. Last week I had to move some server to new hardware and I noticed that postgres databases were transfered with empty data. The database was created in the new server, the user was created, but the database was totally empty. Data was lost. The transfer and restore log shows no error, and the database data was not left in the user's homedir for manual restoration. I also noticed, too late, that cpanel backups are not backing up any postgres databases at all. Here is the transfer log: [2019-08-28 01:31:05 -0300] Performing "Postgresql" component.... [2019-08-28 01:31:05 -0300] Grabbing PostgreSQL databases... [2019-08-28 01:31:05 -0300] ......... [2019-08-28 01:31:06 -0300] Done [2019-08-28 01:31:06 -0300] Grabbing PostgreSQL privileges... [2019-08-28 01:31:06 -0300] Done [2019-08-28 01:31:06 -0300] Completed "Postgresql" component.
And here the restore log: Postgres Preparing PostgreSQL restore " Restoring PostgreSQL users " Creating PostgreSQL databases " Updating PostgreSQL privileges " Restoring PostgreSQL databases " Restoring the database "user_new" " Restoring the database "user_db" " Restoring PostgreSQL grants " Postgres
Both databases user_new and user_db are empty after the transfer. Both databases had it's data inside schemas other then "public" and the "public" schema was empty. The "public" schema was the only one restored. Databases whose data was inside the "public" schema were transfered and restored correctly. Now for the daily backups, there is no log at all for postgres databases, nothing about postgres is mentioned in the logs. I already have a ticket about this issue, just wanted to post it here to share my issue.

    One more thing about the account backups. If I make a backup using /scripts/pkgacct script, the postgres databases are included in the backup file. Only the daily backup is skipping postgres /scripts/pkgacct user /backup/ .....

    Bug confirmed in the transfer tool: I was able to confirm that the schemas outside of public were lost during both the transfer and the back up process. I have submitted a case to our developers at #CPANEL-29288. While I do not have an ETA regarding this you can follow our change log to see updates regarding this case. ====== https://docs.cpanel.net/search/?product=all&q=CL/Change+Logs ====== Until this has been resolved, I would advise taking manaul backups with /scripts/pkgacct as from my testing this keeps the psql database in tact. ...

    Problem in the daily backup confirmed too In my testing forcing the backup process to run resulted in the database not being backed up. ======== /usr/local/cpanel/bin/backup --force ======== The backup script does still utilize pkgacct, and should hypothetically work the same as when pkgacct is run by itself. This does not seem to be the case, unfortunately. The issue also did not appear to be exclusive to Centos, or Cloudlinux as they both had the same result.
    So, manually backup your accounts using postgres if you want to save your data.

    Hello @plague, Thank you for sharing the case number and workaround. I'm monitoring internal case CPANEL-29288 and will update this thread with more information on it's status as it becomes available. Thank you.

    Hello, The internal case associated with this thread was marked as completed and by design. The comments indicated that we only restore the public schema for postgres databases due to an issue with restoring postgres databases on versions higher than 9 [QUOTE] Restore psql databases when using PSQL 9.0 or later Case 183837: Cannot restore postgresql databases on a CentOS 7 server (postgresql-server-9.2.7) When restoring a postgresql database with /usr/bin/pg_restore we need to set an extra option to set the public schema when the server is using version 9.0 or later.
    Ultimately this is due to the fact that postgres was not permitting transfers of non-public schema data and can cause a loss of data. The workaround for this is as you noted as well, to manually back up postgres dbs

    Hello guys. It's been 1 year since my post here about postgres backups. The daily backup is still not backing up postgres databases at all. In 1 year, we still do not have any updates about this?

    Hey @cPanelLauren Your post was about the tranfer and restoring of non-public schemas. The backup problem still exists and is not related to non-public schemas. The daily backup is ignoring postgres databases completely, while manual backups using pkgacct script are fine. This error was confirmed in the same ticket as quoted in my post on "

    This is addressed in the case @plague as well as in the workaround I noted. The transfer tool uses the same backup mechanism the daily backups use, and the reason they are not restored is due to the exact same issue. They are not included in the daily backups due to the issues with restoration.

    @cPanelLauren you still did not understand. Forget about the transfer tool and restoration. The error I am refering to is in the daily backup process. The daily backup is not backing up any postgres databases, even those using public schemas. This was reported and confirmed in the same support ticket on
    Manually invoking /scripts/pkgacct does include postgres databases in the backup. The automatic daily backup does not. That's the problem. On

    @cPanelLauren I have also just discovered that my postgres database has not been included in my daily backups - no public schema, no nothing, the psql folder is empty. However running the cPanel Backup Wizard for the user does include the postgres database, although no indication is given in the wizard - it only mentions the MySQL db. @plague thanks for the script - will use that to do the daily backup until this is sorted.

    @Thornhill Associates - I wasn't able to reproduce this issue on a test server. I created a cPanel account, ensured it had a postgres database, forced the daily backups to run, and confirmed the psql directory had the tar files included. Would it be possible for you to try running this command on the account: /scripts/pkgacct username
    to see if that includes the psql databases on the system? That will create a cpmove file in /home on the system that you can unzip. You'll also see the following section scroll by on the command line as it creates the backup: [2020-12-02 15:37:53 -0500] Performing "Postgresql" component....

    If that doesn't work, it may provide a helpful error as to why that isn't being included on your machine.

    If I run pkgacct the postgres database is backed up correctly. But it isn't backed up when running the daily backup configured in WHM Backup->Backup Configuration

    Do you see anything in the backup log? These logs would be located in /usr/local/cpanel/logs/cpbackup and are sorted according to date.

    @Thornhill Associates - it might be best if we took a look at that. Could you open a ticket using the link in my signature so we can check out the system? If you do that, please post the number here so I can update the community with our findings.

    I completely agree - I've notified our documentation team about that so we can make some adjustments :D

    I have so many questions now.... Why this options is missing from the WHM interface and when will it be available ? Why is this disable by default since it does not make any sense on doing incomplete backups? Why no one from cpanel replied here with this workaround before? I reported this a year ago, I had a ticket opened about this and even the support staff didn't know what to do.

    @plague - I have those same concerns as well. While I can't speak to what happened in your previous ticket that long ago, I have opened a case with our developers to see if they can get me some additional details as to why that isn't included by default. Being a holiday week there might be some delay in getting a response, but I'll be sure to post as soon as I hear back.
