Different dependencies installed for PG13 s390x, mips64le vs amd64, arm64, ppc64le (has some to PG14 rel. packages)

When I running:

on amd64, arm64, ppc64le

docker run --platform=linux/amd64 -ti --rm postgres:13-bullseye bash -c "dpkg -l | grep -i postgresql"
Status: Downloaded newer image for postgres:13-bullseye
ii  libpq5:amd64              14.2-1.pgdg110+1             amd64        PostgreSQL C client library
ii  pgdg-keyring              2018.2                       all          keyring for apt.postgresql.org

ii  postgresql-client-13      13.6-1.pgdg110+1             amd64        front-end programs for PostgreSQL 13
ii  postgresql-client-common  238.pgdg110+1                all          manager for multiple PostgreSQL client versions
ii  postgresql-common         238.pgdg110+1                all          PostgreSQL database-cluster manager

on s390x and mips64le it looks like

docker run --platform=linux/s390x -ti --rm postgres:13-bullseye bash -c "dpkg -l | grep -i postgresql"
ii  libpq5:s390x              13.6-1.pgdg110+1             s390x        PostgreSQL C client library
ii  pgdg-keyring              2018.2                       all          keyring for apt.postgresql.org
ii  postgresql-13             13.6-1.pgdg110+1             s390x        The World's Most Advanced Open Source Relational Database
ii  postgresql-client-13      13.6-1.pgdg110+1             s390x        front-end programs for PostgreSQL 13
ii  postgresql-client-common  238.pgdg110+1                all          manager for multiple PostgreSQL client versions
ii  postgresql-common         238.pgdg110+1                all          PostgreSQL database-cluster manager

Does this make problems?
libpq5:amd64 14.2-1.pgdg110+1 != libpq5:s390x 13.6-1.pgdg110+1

I don't want to try it!

I would expect not to have any postgres14 dependencies for the postgres 13 images

Start by reproducing the posted docker run commands for postgres:13-bullseye on the listed architectures and compare their dpkg -l output. Focus on the libpq5 package versions and determine whether the amd64, arm64, and ppc64le images include an unintended PostgreSQL 14 dependency; done means the architecture-specific package sets are understood and the expected PostgreSQL 13 dependency behavior is established.
