Homebrew OSX Sierra No such PSQL file or directory postgres@9.5

Question

I have a problem starting psqlafter installation using Homebrew

psql: could not connect to server: No such file or directory
    Is the server running locally and accepting
    connections on Unix domain socket "/tmp/.s.PGSQL.5432"?

And they read other messages and tried their suggestions, but nothing happened: 1.

$brew services list

postgresql@9.5 started johndoe /Users/johndoe/Library/LaunchAgents/[e-mail]

2.

$sudo find / -name .s.PGSQL.5432 -ls

1202295        8 lrwxr-xr-x    1 root             wheel                  26 Sep 26 17:09 /private/var/pgsql_socket/.s.PGSQL.5432 -> /private/tmp/.s.PGSQL.5432

3.

$cat /usr/local/var/postgres/server.log

$cd /usr/local/var/postgres
$ls -a

It seems that pidsomewhere, but where? I tried to look in private/var/pgsql_socket, but he was not there. I also disconnected and launched postgres brew.
