Changes between Initial Version and Version 1 of Ticket #37437

-              initial
+              v1

 ```python
+{{{#!python
 import django
 from django.conf import settings
 …
 with connection.cursor() as c:  # OperationalError: couldn't get a connection after 5.00 sec
     c.execute("SELECT current_user")
+```
+}}}

 - In addition, psycopg_pool does not close the connection when `configure`
