The following documentation comment has been logged on the website:

Description:
I'm running an up-to-date version of Manjaro Linux (510 kernel), and
following this guide I wasn't able to find my database files in
/usr/local/pgsql/data, but did manage to find it in /var/lib/postgres/data.
The possibility of it being here is mentioned here:
https://www.postgresql.org/docs/9.3/storage-file-layout.html, but not in the
backup docs. This might be worth mentioning (or linking to the link above)
to make things easier to find for others.
Cheers,
Brendan
