TLS `caCertificates` not working

[jsb188]

Describe the bug

Attempting to connect to database with these options fail with error: "The certificate used to secure the TLS connection is invalid: Bad resource ID"

tls: {
    enforce: true, // Set this to false if using localhost
    caCertificates: [await Deno.readTextFile('./pg-server-ca.pem')],
},

However, this simple connection test succeeds:

const conn = await Deno.connectTls({
    hostname: Deno.env.get('PG_HOST'),
    port: 5432,
    caCerts: [await Deno.readTextFile("pg-server-ca.pem")],
  });

To Reproduce
Try the code/steps above.

Expected behavior
PG should connect, but it does not.
