Re: Performance degradation after upgrading from 9.5 to 14
1) How did you upgrade? pg_dump or pg_upgrade? I use pg_ugrade with kink option. 2) Did you run ANALYZE to collect statistics after the upgrade? Yes. I ran vacuumdb-analyze in stages after the upgrade 3) Did you transfer the configuration, or did you just create a new cluster with the default values? I transfer the configuration 4) What exactly is slower? Queries? Inserts? queries 5) Can you quantify the impact? Is it 2x slower? 100x slower? it's more than 5 times slower than before.

Performance degradation after upgrading from 9.5 to 14
Hello, I performed an upgrade from postgresql-9.5 to postgresql-14 and the performance has degraded drastically. Please, is they any advice on getting performance back ? King Regards Johnathan T.
Postgres database encryption
Hello, Good morning. Please I wish to find out the best way of encrypting a Postgres database. This could either be encrypting a whole database ( I don’t if this is possible), a specific table and a specific tablespace. King regards Johnathan T.

Re: Safest pgupgrade jump distance
I have upgraded from 9.5 to 14 using the -link option. It works fine. I equally had streaming replication running on it. I break(split brain) replication and upgrade the standby, once it done and everything is running smoothly, I then install version 14 to the old primary and just configure streaming on it and all now runs on 14.

Re: pg_basebackup Restore problem
1. What's in $PATH_FOLDER?
/tnt/backup/current
2. What pg_basebackup command did you use?
pg_basebackup -D "$baseback_dir" --format=tar \
"${comp_opts[@]}" --wal-method=stream --no-password
--verbose "${PG_DUMP_OPTS[@]}"
/bin/mv "$baseback_dir"/* "/enf/backup/current/"

Re: pg_basebackup Restore problem
You need to tell us the PG version number *and* show us the full command
you ran. ?
Postgresql Version 14.10
tar -h -zxvf $PATH_FOLDER/* .tar.gz
ls $PATH_FOLDER/*.tar.gz | xargs -I {} tar -h -zxvf {}
What user are you running pg_basebackup as?
I ran it as postgres and now I'm restoring as postgres
/tnt??? Or /mnt?
/tnt/backup/current
This is where the backup files are.

ERROR: missing chunk number 0 for toast value 1563962066 in pg_toast_2619
Hello, Please, I need help to fix this. Can't do anything in the database. This error keeps popping up. I have tried to do a pg_dump and the same error keeps coming up. Thank you Johnathan Tiamoh
Re: Unable to start postgresql-14
Was this backup taken before the data directory was deleted? Yes. I restored it from a 1-day old backup, but unfortunately, I couldn't apply the logs. If so how was the backup done? It was taken with a customized script that uses pg_dump. Does this mean you recreated the data directory from some source and then ran pg_resetwal? I recreated it from the backup Do you mean you did a pg_dumpall from the Postgres instance running on the restored data directory? Yes.

Re: Unable to start postgresql-14
More information needed: 1) Exact Postgres version e.g 14.x Postgresql Version 14. 10 2) Is it community version or fork? Community version 3) What was the command you used to start the cluster? systemctl start postgresql-14 4) Do you have replication/WAL archiving set up? Yes. Just to add. The data directory was accidentally deleted. At the time of deletion. The secondary was broken. I restore from backup and it couldn't start. I ended up doing a pg_resetwal to start it and ended up with lots of data corruption. I have try a pg_dumpall to restore in a new server and it has equally failed.

what do you do after pg_walreset ?
Hello, Please I wish to find out what you do after running pg_walreset. I made a mistake and deleted my data directory with all its content. I then restore with 1 day old backups, after that i could start unless i did pg_walreset. 1, I wish to find out what to do after i have started postgresql ? 2, How do I apply the wall files after the reset ? 3, How can I determine the amount of data lost ?

Re: Need Help On Upgrade
Hello Adrian 1) PgBouncer version. pgbouncer.1.7.2 2) Did you change the settings when going from 9.5 to 14.8? No. I did not do any configuration changes on the bouncers 3) Does the PgBouncer log show anything relevant? No. It does not show anything 4) Does '...through the pgbouncers...' mean there is more then one PgBouncer instance in use? Yes, I have more than 3 pgbouncers for different connections.

Re: Need Help On Upgrade
Hello KK, In the beginning, it was a little challenging, but as the process went on it became easy. No, it was not a multistage upgrade. It was possible to upgrade straight from 9.5 to 14. We did not change anything on the schema. For data type, we alter all tables that were created with OIDs to remove the OIDs. We remove all data with abs time ( absolute time). We equally remove all data with sql_identifier. We also created a script to check for unknown data type and another to remove them. For documentation, we did not use any specific documentation. We just followed postgresql documentation on upgrading. We created our one plan and steps based on our clusters, ensuring we can safely roll back in case of any challenges. Thank you.

Need Help On Upgrade
Hello, I upgraded from postgresql 9.5 to 14.8. After the upgrade users were not able to connect due to password hash. The password encryption was on scram-sha-256. The password hash was on md5. in the pg_hba.conf file the authentication method was md5. I do not know why users could not connect because as per postgresql documentation, that should work. I have previously done a similar upgrade and did not face similar issues. Kind regards Johnathan Tiamoh
