I have restored a backup from psql server A to psql server B. When the postgresql service starts on server B, the log below is produced. From what I read the invalid record length message is not a problem, just an indicator that the end of the last WAL file was reached.
However, when I attempt to run 'psql' it gives a fatal error that the database is starting up. (I waited over an hour and still in that state). I still can't run psql. Note that standby.signal file is present on B, in case that matters.
What does this mean, and how do I fix it? Or is this normal while the standby.signal file is present?

Is there any way we could stop replication without logging into psql shell.
Disk-full situation lead to some corruption in PG files and keep on restarting.

Tried removing pg_replslot/slot_name which lead to "password auth failure" and After resetting DB password(via pg_hba.conf) DB is not showing up !
Is there any proper way to recover in this state? /pg/main files and pgdata directories seem to be available except this slot information.
Done below steps:
I'm using PSQL docker container.
disk used for PG got full. Cleaned up some log files and docker system prune was used to remove unused images which freed some space. But lead to this issue.
Multiple times, we have seen similar issue in Dev environments, Disk full leading to some corrupted files (unable to read/ No such file or directory) kind of errors.
Tried removing pg_replslot/slot_name directory and it allowed me to start PSQL container.(previously is was keep on restarting container)
Reset password by using trust in auth column in pg_hbda.conf.
Now \l in psql shell showing only postgres DB and default DB's. Not showing our custom DB.
We have main DB in a separate tablespace and is not showing up in the list.
_ MOST importantly, Standby is also having SAME errors ! Probably someone messed it?
In the Datastore logs, I encountered the following error, Not sure what has gone wrong.

Somebody deleted crucial WAL files (to free space?), and now your cluster is corrupted
Restore from backup. If you have no backup, running pg_resetwal is an option, since it seems there was a clean shutdown.
I am trying to run postgreSQL via docker-compose and I am getting the issue that user/password is not created when I started the service.
version: "3"
services:
db:
image: postgres:latest
container_name: postgres
#volumes:
#- postgres-data:/var/lib/postgresql/data
ports:
- 5432:5432
environment:
- POSTGRES_PASSWORD=postgrespassword
- POSTGRES_USER=postgres
- POSTGRES_DB=random_db_name
restart: always
I have this block of code in my docker-compose.yml and I run the following command:
docker-compose up -d (this allow me to start the service in background)
and when I check the logs I got:
docker logs -f 0e1731f95396
The files belonging to this database system will be owned by user "postgres".
This user must also own the server process.
The database cluster will be initialized with locale "en_US.utf8".
The default database encoding has accordingly been set to "UTF8".
The default text search configuration will be set to "english".
Data page checksums are disabled.

Success. You can now start the database server using:
initdb: warning: enabling "trust" authentication for local connections
You can change this by editing pg_hba.conf or using the option -A, or
--auth-local and --auth-host, the next time you run initdb.

But when I try to connect to this database locally I get the message: "FATAL: role "postgres" does not exist"
Do you have any input about how to solve this problem?
I already made a few attempts after reading a few comments from different places but I got always the same problem.
I was expecting to run locally postgreSQL and setup already a user/password and a Database with that name in the docker-compose
I have edited my pg_hba file and copied it to server and restarted the services by "sudo service postgresql restart" but after that the server is not connecting.
Showing the below error, Your database returned: "Connection to 138.2xx.1xx.xx:5432 refused. Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections."
The Jenkins job and data visualization tools are failing which was working fine previously. What could be the reason.

Do i need to restart the entire server?
Can anyone please help me to resolve this.
I have a database stored on an external hard drive. The database was created using PostgreSQL 11, on an Ubuntu 18.04 machine. The folder it's stored in was the data directory of my PostgreSQL instance on my Ubuntu machine, everything worked fine. I don't have access to this Ubuntu machine anymore, and this will last for a few months, but I have the external drive. I'm working under macOS 14.6 in the meantime. I setup PostgreSQL on my Mac using the Postgres.app. I created a new server, making sure to use version 11. The defaut data directory was of course not the one I want, so I changed its path in postgresql.conf to point to my existing data dir:
data_directory = 'path_to_external_HDD_data_directory'
Note that this is all I changed in the .conf file (should I change anything else?). When I try to connect to the server via Postgres.app, I get the following error:
pg_ctl: server did not start in time
And the log is:

Postgres.app then tells me that the port is in use. Running lsof -n -i4TCP:5432, I see that postgres is listening. I killed it and retried but got the same pg_ctl error. Any idea of what I can do?
Your server started successfully. You don't use pg_ctl to connect to PostgreSQL, but the command line client psql.
Anyway, you should stop what you are doing right now before any damage is done.
It is not supported to use a PostgreSQL data directory created with one architecture (Linux) on a different architecture (MacOS).
If the server starts, it is by coincidence. Connecting might work, but it might just as well corrupt your database.
