I was asking him, because in Patroni, u need to install pgbackrest in each and every node of patroni, then have a dedicated server for pgbackrest repository, and set the configuration to allow pgbackrest to take backup from patroni nodes, then finally u have to set the archive_command and restore parameters in patroni yaml files in each node, that's it so far I guess. Correct me if I am missing something, pls

Читать полностью…Good evening, maybe someone can guide me, I have a cluster where connections are made through pgpool on port 9999 using a virtual IP, I want to create a user that connects through the virtual IP and is only read-only, it gives me this error Unable to connect to server connection failed to server 192.168.15.145 port 9999 failed error failed to authenticate with backend using scram detail valid password not found, I already created the user but when I use postgres port 5432 it does allow me to connect but I don't want it there, I want it through port 9999 so that it does the correct pgpool balancing, how could I do where should I create the user? In pgpool_hba.conf?? Where and the postgres encryption method is scram, and pgpool md5, can someone explain to me if it is possible and what I am doing
Читать полностью…I have checked the replication slot and there is no abondoned slot. Also before no archiving was there but I set it now. But the issue is if all 539 gb wal files will copy to remote server , it will fail because not enough space. So this is the scenario. How to tackle this
Читать полностью…Can anyone pls help. My whole motto is to reduce the pg_wal size without affecting replication and archiving. How to achieve this?
Читать полностью…Thank u for all information but I am still confused how to reduce size of pg_wal on master server. After setting archive command on master it will copy the wal files to a remote server and if it copies all files of 539 gb to remote server, it will fail because remote server has not this space.
So in this scenario what should I do to to reduce pg_wal size till 50 gb
Patroni just manages Postgres. No difference there.
But you can benefit from pgbackrest in your Patroni config, e.g. for initial cloning etc. There are examples in the Patroni docs, check them out.
temp tables are written into a special schema, on disk. But they are not WAL logged (i.e. not sync
ed), so they essentially reside in the shared buffers, if they grow larger they end up in the OS' filesystem cache and *may* spill to the filesystem.
N.B.: the catalog changes related to TEMP tables *are* WAL logged.
That may well be your problem... 5-10 days might be the patch & reboot cycle in your organisation. I've worked in several large shops that rebooted each Window$ machine (including servers) every weekend.

Читать полностью…Dear collegues, hello
Could anyone tell me which component of memory(RAM, disk) stores temp tables in postgres?
As i know, temp tables are storing while the session or transaction is alive
So in this case where temp tables are storing?
Can I manually delete 2 months older wal files from pg_wal on master if I take full hot backup everyday? Will it cause any error on replication or anything else?
Читать полностью…I will say it once again, the database will not delete a wal segment until:
- it has been succesfully archived
- there are no more replication slots needing that segment
If you have >500gb of of wal segments, check the logs because something is going very wrong in your setup
Ok. It means suppose I set wal keep size to 50 gb. Will it reduce the pg_wal size to 50 gb from 539 gb?
