Bug report

LISTEN / NOTIFY appears to be broken after March 26th

• I confirm this is a bug with Supabase, not with my own application.
• I confirm I have searched the Docs, GitHub Discussions, and Discord.

Describe the bug

We have an Elixir application that uses Oban for job processing that connects to a supabase postgresql instance via transaction pooling.

Oban makes extensive use of LISTEN/NOTIFY, which has been working without issue for 2 months.

As of March 26th all most listen/notify requests started to fail.
