Hi,
> FATAL: could not open lock file "/tmp/.s.PGSQL.5432.lock": Permission
> denied
I got that error today.
My case:
I installed psql using user A, then I uninstalled it.
I installed psql using user B and I got that error.
Reason: The lock file in /tmp was owned by user A
Solution:
su and rm the lock file :)
End of case
