It looks like the `postgres` user doesn't have permissions to write into the `/run/renderd` directory and/or it doesn't exist. First check if that directory (`/run/renderd`) exists and is writable.
```shell
$ sudo -u postgres ls -al /run/renderd
ls: cannot access '/run/renderd': No such file or directory
```
If not, you'll need to create it:
```shell
$ sudo mkdir /run/renderd
```
Then, whether it existed or not, grant `postgres` write permissions to it:
```shell
$ sudo chown postgres:postgres /run/renderd
```

You'll probably have a similar issue with the `tile_dir`, so do the same thing for `/var/cache/renderd/tiles`:
```shell
$ sudo -u postgres ls -al /var/cache/renderd/tiles
ls: cannot access '/var/cache/renderd/tiles': No such file or directory
$ sudo mkdir -p /var/cache/renderd/tiles
$ sudo chown postgres:postgres /var/cache/renderd/tiles
```
