PostgreSQL 10 not able to start on Mac - postgresql

I'm running PostgreSQL 10 on a mac running macOS Mojave 10.14.1, i'm getting a could not start PostgreSQL server, pg_ctl could not start server.1
and the log shows: 2
-LOG: listening on IPv6 address "::1", port 5432
-LOG: listening on IPv4 address "127.0.0.1", port 5432
-LOG: listening on Unix socket "/tmp/.s.PGSQL.5432"

-PANIC: could not locate a valid checkpoint record
-LOG: startup process (PID 3462) was terminated by signal 6: Abort trap
-LOG: aborting startup due to startup process failure

Just wondering if anyone has seen something similar to this.
Thanks

Your database or wal are corrupted. Normally it could fix itself unless it is very bad. Is it a new database? If so, delete it and recreate.

Postgresql - PANIC: could not open file "pg_replslot/slot_name/state": No such file or directory

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?

terminating connection because of crash of another server process

We are facing this issue with POSTGRES 12.11, only on windows OS, with Linux OS, it works fine,
if the executable that is using the database session crashes, then the entire database goes to recovery mode and restarts, in the Postgres log, we can find the below messages.
2022-10-06 17:44:09.210 CEST [8860] LOG: server process (PID 9980) exited with exit code 0
2022-10-06 17:44:09.210 CEST [8860] LOG: terminating any other active server processes

2022-10-06 17:44:09.211 CEST [9992] HINT: In a moment you should be able to reconnect to the database and repeat your command.
and then it goes to recovery mode.
any idea or workaround to avoid this issue? and if the Postgres crashes, where does the crash dump gets generated in the windows?

pg_Ctl -data directory has wrong ownership

I am unable to start the Postgres server and whenever I use pg_ctl I am getting the following error - can some one help me to fix this. I changed the folder permissions using CHmod and tried running with Sudo -s also but still the problem exists.
one error I did was, I deleted the Postmaster.pid when the server was running- post this I am getting this issue when ever I try to start the server through pg_ctl and another error when I use the pgadmin.
Any suggestions here will be really helpful- thanks.
Using Macos Shell command :

Using pgadmin the error is as follows :
'could not connect to server: Connection refused Is the server running on host "localhost" (::1) and accepting TCP/IP connections on port 5434? could not connect to server: Connection refused Is the server running on host "localhost" (127.0.0.1) and accepting TCP/IP connections on port 5434?'
p.s. : I modified the hba.conf and also the postgres.conf files to allow connection from the local ip

The data directory should be owned by the postgres user and have user-only access (700 or u+rwx)
Does this match what you have set up?

Change PostgreSQL data directory to directory created by PostgresSQL on another machine

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.

When insert rows using python psycopg2, docker postgres process is terminated

Database is postgresql-9.5.1 in docker. My host machine has 3.75 GB memory, linux. In some methods I am inserting 490000 rows one after another using psycopg2 with below code.
student_list = [(name, surname, explanation)]
args_str = ','.join(cur.mogrify("(%s,%s,%s)", x) for x in student_list)
cur.execute('INSERT INTO students (name, surname, explanation) VALUES ' + args_str)
This makes my database docker memory seems full and gives these errors:
LOG: server process (PID 11219) was terminated by signal 9:

I tried put some sleep time between consecutive queries but got same result. Is there any limitation for that?
Also I tried to connect and disconnect for each query but got same result. These are my connect and disconnect methods.
def connect():
conn = psycopg2.connect(database=database_name,
user=database_user,
host=database_host,
port=database_port)
conn
.set_isolation_level(psycopg2.extensions.ISOLATION_LEVEL_AUTOCOMMIT)
cur = conn.cursor()
return conn, cur
def disconnect(conn, cur):
cur.close()
conn.close()
Here is what I did. Actually my memory was full enough. That's why linux OS used to kill the process in Postgresql. There were 1M values in every insert process. The trick was I divided data lists to chunks and tried it 100k by 100k. That works very well. Thanks for your helps.
