Most likely it's because your system shutdown unexpectedly Try
<pre><code class="lang-sh">postgres -D /usr/local/var/postgres # for Intel M1
postgres -D /usr/local/var/postgres # for Silicon
</code></pre>
You might see
<pre><code class="lang-sh">FATAL: lock file "postmaster.pid" already exists
HINT: Is another postmaster (PID 449) running in data directory "/usr/local/var/postgres"?
</code></pre>
Then try
<code>kill -9 PID</code>
example
<code>kill -9 419</code> And it should start postgres normally

Most likely it's because your system shutdown unexpectedly Try

```sh
postgres -D /usr/local/var/postgres # for Intel M1
postgres -D /usr/local/var/postgres # for Silicon
```

You might see

```sh
FATAL:  lock file "postmaster.pid" already exists
HINT:  Is another postmaster (PID 449) running in data directory "/usr/local/var/postgres"?
```

Then try

`kill -9 PID`

**example**

`kill -9 419` And it should start postgres normally
