0kb backup files with DEFAULT_PARALLEL_COMPRESSION_THREADS set to incorrect value

[Maypul]

Summary

Hi, I have noticed, both for Postgres and Maria DB, when I had set DEFAULT_PARALLEL_COMPRESSION_THREADS to a wrong value (initially I left it at 'autodetected' and forgot to change), the container did not report any error, but when scheduled backup started, it also completed without errors but all backup files had 0 kb. Once I commented out this variable, all backups have sizezs.

Steps to reproduce

In the compose, set DEFAULT_PARALLEL_COMPRESSION_THREADS to a wrong value, for example:
DEFAULT_PARALLEL_COMPRESSION_THREADS: autodetected

What is the expected correct behavior?

Backups have some sime, not 0 kbs.

Relevant logs and/or screenshots

The logs in console all "normal", as they end with no errors, just complete instantly.

Environment

Docker

• Image version / tag: latest
• Host OS: Synology DSM NAS OS

Possible fixes

I would guess the container should maybe error out if the variable has not possible value for it to use?
