Thread: Nu-B here
After this command 'sudo -u postgres psql'
I get this message :
could not change directory to "/home/my_account": Permission denied
psql (12.15 (Debian 12.15-1.pgdg120+1))
Type "help" for help.
I tried using help, but to no avail.
What am I doing wrong?
Thanks in advance!

This is normal if you launch psql via "sudo -u postgres" in a directory
that the postgres user doesn't have permissions to read/chdir to.
psql will still start, but its working directory will not be what
you'd expect, so commands that involve local filesystem access might
misbehave.
We have a fix for this error report in the upcoming v16, but psql commands
that involve local filesystem access will still not act very nicely if
psql can't read your directory.

It looks like you're hitting a non-fatal error at some point during psql startup when you're running as the "postgres" user. It seems to be a permissions issue. Do you still get the error if you run
sudo -u postgres psql --no-psqlrc
?
You may also want to create a Postgres user (possibly a superuser) matching your operating system user if you have not already done so to avoid having to deal with sudo for connecting.
Thanks

If you’re simply trying to connect to the database named postgres as database user postgres, you can instead use the command'psql -U postgres postgres’.

What’s the reason that you’re using the OS user postgres?
Because the Debian/Ubuntu packaging sets up pg_hba.conf to use peer auth for local connections and the only database user created is postgres.

If you’re simply trying to connect to the database named postgres as database user postgres, you can instead use the command 'psql -U postgres postgres’.
