From 93c82d0e6a252dc2fb6d6c7ed240508140cd1480 Mon Sep 17 00:00:00 2001 From: Nathan Bossart Date: Fri, 9 Aug 2024 10:52:37 -0500 Subject: [PATCH] doc: Fix name of CRC algorithm in "Reliability" section. This section claims we use CRC-32 for WAL records and two-phase state files, but we've actually used CRC-32C since v9.5 (commit 5028f22f6e). Fix that.
