Re: postgresql.conf.sample tab width

Hi Nathan,

I just reviewed the patch. Looks to me the correct three-commit split:

0001 updates tooling/configure so that 0002 will not introduce formatting violation
0002 makes large formatting rewrite (tab->white spaces), and so that the commit needs to be added to .git-blace-ignore-revs
0003 adds CI enforcement so that no future patches to reintroduce tabs

A tiny comment about a typo in 0003’s commit message:
```
The previous commit updated this file to use tabs instead of
spaces.
```

Should be “use spaces instead of tabs”.
