[Amn Ojee Uw <amnojeeuw@xxxxxxxxx>]

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!
