+By default, Supabase requires IPv6 connections.
+This restriction can be bypassed using the "transaction pooler".
+You can get its connection string from the Supabase "Connect to your project" UI.
+It looks something like this: `postgresql://postgres.zlltjtdocmcqiqprpunq:[YOUR-PASSWORD]@aws-1-eu-north-1.pooler.supabase.com:6543/postgres`
