Password is getting appended to the hostname
### Summary

When connecting to the database, I get an ENOTFOUND error. The URL it outputs as being incorrect is my password appended to the beginning of my hostname, literally like: "${password}${hostname}". This has been working for weeks and the issue just started this morning and I didn't change anything. I deleted `node_modules` and `yarn.lock` and reinstalled to no avail.

```
apiRouter.use(
  postgraphile(
    {
      database: process.env.PG_DB,
      port: +(process.env.PG_PORT || '25060'),
      host: process.env.PG_HOST,
      password: process.env.PG_PASSWORD,
      user: process.env.PG_USER,
      ssl: {
        rejectUnauthorized: false,
        ca: process.env.PG_CERT
      }
    },
    'public',
    {
      watchPg: true,
      graphiql: true,
      enhanceGraphiql: true,
      appendPlugins: [ConnectionFilterPlugin, PgMutationUpsertPlugin]
    }
  )
);
```

I've quadruple checked my environment variables that they are indeed correct. I even tried entering the exact fields without the variables and that still does the same thing. Somehow, Postgraphile is appending the password to the hostname before connecting.
