Please provide the following information when submitting an issue (feature requests or general comments can skip this):

1. pgBackRest version: 2.51

2. PostgreSQL version: 14

3. Operating system/version - if you have more than one server (for example, a database server, a repository host server, one or more standbys), please specify each: FreeBSD 13.3

4. Did you install pgBackRest from source or from a package? From source

5. Please attach the following as applicable:

   • pgbackrest.conf file(s)
   • postgresql.conf settings applicable to pgBackRest (archive_command, archive_mode, listen_addresses, max_wal_senders, wal_level, port)
   • errors in the postgresql log file before or during the time you experienced the issue
   • log file in /var/log/pgbackrest for the commands run (e.g. /var/log/pgbackrest/mystanza_backup.log)

6. Describe the issue:

I can backup successfully from shell (tcsh and /bin/sh) from pgbackrest user.
When pgbackrest is executed from pgbackrest cron, it doesn't load config from files located in /usr/local/etc/pgbackrest/conf.d/
Using truss from cron I see pgbackrest to look for pgbackrest.conf only filename in different paths.

When pgbackrest is executed from pgbackrest cron, it doesn't load config from files located in /usr/local/etc/pgbackrest/conf.d/

So where does it try to load them from?
