BUG #13642: no backup_label file in PG_DATA after pg_stop_backup(); - Mailing list pgsql-bugs

The following bug has been logged on the website:

Bug reference:      13642
Logged by:          Amir Rohan
Email address:      amir.rohan@mail.com
PostgreSQL version: 9.4.4
Operating system:   Linux
Description:

SELECT pg_start_backup('backup1');
SELECT pg_stop('backup1');

Doesn't create the `backup_label`  described in the docs (I'm assuming
"cluster directory" means data directory, e.g. $PGDATA):
http://www.postgresql.org/docs/current/static/continuous-archiving.html

They further state:
"The file is critical to the integrity of the backup, should you need to
restore from it."

Are my backups safe or not?
