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?

We have an application pipeline and Postgres-12(TimescaleDB, managed through Patroni) on a separate server (VM with Ubuntu 18.04 LTS).
We are facing an issue with the DB, it suddenly stuck in the recovery mode, and also we can’t access it from the psql client and select queries also hung.
After an hour or late all got back to normal (As my current pipeline terminated) and able to run queries against the DB server.

Please any advise on this issue?
What version of TimescaleDB are you running? In particular, there were some issues with 1.7.x if you try to query a read replica; we recommend upgrading to 1.7.4.
(Otherwise, there's not much information about to suggest what might have happened.)
https://github.com/timescale/timescaledb/releases/tag/1.7.4
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.
i have an old copy of my postgresql db folder (/var/lib/postgresql/9.5/main/) from my server. Now I want to get the data out of the files. So i copied the main folder to my local machine and changed the postgresql config (/etc/postgresql/9.5/main/postgresql.conf) to point to that directory. Also i changed the permission of the main directory to the user postgres. After restarting the postgresql service (sudo service postgresql restart) it doesn't really work.
What I'm doing wrong? (Yea I know, pg_dump is the preferred way, but in this way...)
So my question, does this even work?
Or is there a other way to get the data out of this?
everything is done on ubuntu 16.04.
Edit:
the log file after changing the postgresql.conf file to point to the new directory.

Ok that pointed me to this. The server is a armv7l, whereas the local machine is x86_64 (uname -m). So there is no chance to get the data out of it?
thx, Luc
If it's really true that your data directory is from an ARM7l system, and your local system is x86_64, you're going to have some difficulties.
The immediate error about USE_FLOAT8_BYVAL is because ARM7L is 32-bit, and cannot pass 64-bit floating point values (8 byte) by-value. Your 64-bit host can. But if you recompiled a custom postgres with USE_FLOAT8_BYVAL disabled you'd likely just run into other issues.
I suggest installing PostgreSQL on a matching ARM system to recover the data. Data directories for PostgreSQL are not portable across architectures (for performance reasons).
If you do not have access to the ARM system anymore, an emulator like qemu should be able to help you.
Otherwise, maybe you can compile a modified PostgreSQL (probably starting with 32-bit x86) that can read the data-dir, with appropriate configure options etc. I've never needed to try this.
