v1-0009-WIP-Use-streaming-reads-in-vacuum.patch

From faa521e91fda707b5f3ac2f760c5bd70ae66b53b Mon Sep 17 00:00:00 2001
From: Andres Freund <andres@anarazel.de>
Date: Wed, 12 Apr 2023 15:44:19 -0700
Subject: [PATCH v1 09/14] WIP: Use streaming reads in vacuum.

XXX Cherry-picked from https://github.com/anarazel/postgres/tree/aio and
lightly modified by TM, for demonstration purposes (I still need to
understand why regress/regress's stats test reuse counter doesn't like
this).
