logto: bug: Connection to SSL DB: Error: self signed certificate in certificate chain

Describe the bug

I use a DigitalOcean Managed Postgres database for the deployment, but get the following error when starting the logto container:

Error while initializing app Error: self signed certificate in certificate chain
at TLSSocket.onConnectSecure (node:_tls_wrap:1535:34)
at TLSSocket.emit (node:events:513:28)
at TLSSocket._finishInit (node:_tls_wrap:949:8)
at TLSWrap.ssl.onhandshakedone (node:_tls_wrap:730:12) {
code: 'SELF_SIGNED_CERT_IN_CHAIN'

Expected behavior

Logto should be able to connect to SSL only databases.

How to reproduce?

1. Get a hosted DB at DigitalOcean
2. Configure the Logto Docker Container like this

Alright tried

I tried to use the following env vars to circumvent the problem:

- NODE_TLS_REJECT_UNAUTHORIZED='0'
- PGSSLMODE=no-verify

Context

OS: Linux Docker: ghcr.io/logto-io/logto:1.0.0-beta.6
