Specify CA certificate manually

[baoshan]

With deno-postgres, I can specify a .crt file (e.g., supabase.crt), and sslmode=require works (tested just now).

Is this an option for Postgres.js?

Yes indeed it is, just use caCerts options as specified in the deno docs in your ssl object like this:

const sql = postgres(url, {
  ssl: {
    caCerts: [await Deno.readTextFile('./cert.pem')]
  }
})

BTW, in Node.js you can use { ssl: { ca: [ fs.readFileSync('server-cert.pem') ] }}, see https://nodejs.org/api/tls.html
