Deleted Namespace is still listed with state Registered

[denniskniep]

Actual Behavior

If a namespace is created, deleted, created and again deleted, then there is sometimes the behavior, that temporal cli reports:

Error: unable to delete namespace: Namespace has invalid state: Deleted. Must be Registered or Deprecated.

But an invocation of list command will return that the namespace is registered:

NamespaceInfo.Name                    test0815 
NamespaceInfo.State                   Registered 

Expected Behavior

Namespace state should be "Deleted" OR Namespace should be removed after a delete call

Steps to Reproduce the Problem

start this file with docker-compose

version: "3.8"
services:
  temporal:
    image: temporalio/auto-setup:1.22.3.0 
    container_name: temporal-for-tests
    environment:
      - DB=postgres12
      - DB_PORT=5432
      - POSTGRES_USER=temporal
      - POSTGRES_PWD=temporal
      - POSTGRES_SEEDS=postgresql 
    ports:
      - 7233:7233
    depends_on:
      - postgresql

  postgresql:
    image: postgres:13
    environment:
      POSTGRES_PASSWORD: temporal
      POSTGRES_USER: temporal    
    ports:
      - 5432:5432
    volumes:
      - /var/lib/postgresql/data

I wrote a little bash script to reproduce the problem. It consistently reproduces the issue for me. Please let me know if this is not the case for you:

while true; do sleep 1;temporal operator namespace create test0815; temporal operator namespace delete -y test0815; temporal operator namespace list; echo "###########################"; done
