The permissions on the socket file /tmp/.s.PGSQL.5432.
Ordinarily the postmaster will create the socket as world-writable,
but evidently not this time. Perhaps you have set a nonstandard value
for "unix_socket_permissions"? Another possibility is that it's not
the socket file itself, but /tmp that is mis-permissioned.
