I've been trying to connect to Supabase, got help from an agent to but couldn't resolve the issue and connect :/

What’s actually broken

DB Pro:

Enforces strict TLS verification

Uses its own certificate trust bundle

Does not:

read macOS System Keychain reliably

allow custom CA injection

allow “require but don’t verify”

Supabase pooler requires either:

trusting Supabase’s CA, or

allowing non-verified SSL

DB Pro supports neither.

So it fails with:

self signed certificate in certificate chain

This is a product limitation / bug in DB Pro.
