pg_dump from Celery container differs from pg_dump in other containers - postgresql

Question

I can't understand where pg_dump version is coming from.
I forced everywhere postrgresql-client-13 to be installed.
/usr/bin/pg_dump --version
Celery Beat and Celery
pg_dump (PostgreSQL) 11.12 (Debian 11.12-0+deb10u1)
Other containers (web & postgre and local machine) :
pg_dump (PostgreSQL) 13.4 (Debian 13.4-1.pgdg100+1)
Here is my Dockerfile
FROM python:3
#testdriven turotial they use an other user than root but seemed to fail ehre .
# create directory for the app user
RUN mkdir -p /home/app
ENV HOME=/home/app
ENV APP_HOME=/home/app/web
RUN mkdir $APP_HOME
RUN mkdir $APP_HOME/staticfiles
WORKDIR $APP_HOME

I really need to have Celery with the same pg_dump version.
Can you guys provide some inputs ?
