Here is a rebased patch set. Notably, I've split it into three pieces.
I'm planning to add 0002 to .git-blame-ignore-revs, as testing indicates
this preserves the blame history reasonably well.

Subject: [PATCH v3 1/3] Update .editorconfig and .gitattributes for
postgresql.conf.sample.
This commit updates .editorconfig and .gitattributes in preparation
for a follow-up commit that will modify this file to use tabs
instead of spaces.

Subject: [PATCH v3 2/3] Switch from tabs to spaces in postgresql.conf.sample.
This file is written for 8-space tabs, since we expect that users
who are editing their configuration files are using 8-space tabs.
However, most of PostgreSQL is written for 4-space tabs, and at
least one popular web interface defaults to 4-space tabs. Rather
than trying to standardize on a particular tab width for this file,
let's just switch to spaces.

From: Nathan Bossart <nathan@postgresql.org>
Date: Mon, 17 Nov 2025 11:48:57 -0600
Subject: [PATCH v3 3/3] Check for tabs in postgresql.conf.sample.
The previous commit updated this file to use tabs instead of
spaces. This commit adds a test to ensure that no new tabs are
added.
Reviewed-by: Tom Lane <tgl@sss.pgh.pa.us>

Subject: [PATCH v3 2/3] Switch from tabs to spaces in postgresql.conf.sample.
This file is written for 8-space tabs, since we expect that users
who are editing their configuration files are using 8-space tabs.
However, most of PostgreSQL is written for 4-space tabs, and at
least one popular web interface defaults to 4-space tabs. Rather
than trying to standardize on a particular tab width for this file,
let's just switch to spaces.

Subject: [PATCH v3 3/3] Check for tabs in postgresql.conf.sample.
The previous commit updated this file to use tabs instead of
spaces. This commit adds a test to ensure that no new tabs are
added.
