Ansible module postgresql_query gives error - postgresql

Question

I have a code like this:
- name: Check if postgres is running
community.postgresql.postgresql_ping:
db: "{{ stl_database }}"
port: "{{ stl_postgres_port }}"
login_host: "{{ db_host }}"
login_password: "{{ postgres_password }}"
register: postgres_availabe
- name: Check the database versions
postgresql_query:
db: "{{ stl_database }}"
port: "{{ stl_postgres_port }}"
login_host: "{{ db_host }}"
login_user: postgres
login_password: "{{ postgres_password }}"
query: "{{ get_db_version }}"
become: yes
become_user: postgres
register: db_version_return
when: postgres_availabe.is_available == true
It uses two community modules which I have installed with ansible-galaxy collection install community.postgresql.
The first module checks if postgresql is running on the remote server {{ db_host }}, the second module run a query(defined by {{ get_db_version }}) to get the code version from the postgresql DB on the remote server {{ db_host }}. When I run the code, I am getting the below output:

The first module works. But the 2nd one errors. When I use "-vvv" in the CLI and I got the details like this:

It looks like the module is trying to do chmod +a and chmod A+user:postgres:rx:allow. If I manually try the commands, I got:
chmod A+user:postgres:rx:allow rename_appdb.sql
chmod: invalid mode: ‘A+user:postgres:rx:allow’
Try 'chmod --help' for more information.
Any idea why the module is doing that? I have the same code running on another ansible server that I used before and it has been working(still today). But when I try to run this on a new ansible server that I installed the community modules yesterday, I got the errors above.
Thanks!

Answer 1

As β.εηοιτ.βε suggested, I removed the become and become_user from the code and it works.
The new code:
- name: Check the database versions
postgresql_query:
db: "{{ stl_database }}"
port: "{{ stl_postgres_port }}"
login_host: "{{ db_host }}"
login_user: postgres
login_password: "{{ postgres_password }}"
query: "{{ get_db_version }}"
register: db_version_return
when: postgres_availabe.is_available == true
and the result:
