should postgresql-common depend on ca-certificates?

If I follow the Quickstart at
https://wiki.postgresql.org/wiki/Apt#Quickstart but use
--no-install-recommends, things don't quite work. (I realize I'm going
off the well-trodden path, but this is useful for CI setups to avoid
installing packages you don't strictly need.) For example, on Ubuntu 24.04:

apt-get update
apt-get -y --no-install-recommends install gnupg postgresql-common
/usr/share/postgresql-common/pgdg/apt.postgresql.org.sh -y

Then you get warnings like this:

Certificate verification failed: The certificate is NOT trusted. The
certificate issuer is unknown. Could not handshake: Error in the
certificate verification. [IP: 151.101.3.52 443]
W: https://apt.postgresql.org/pub/repos/apt/dists/noble-pgdg/InRelease:
No system certificates available. Try installing ca-certificates.

When you install ca-certificates, then the whole thing works.
Apparently, there is a "recommends" dependency somewhere down the chain,
but postgresql-common itself doesn't mention it.

I don't know what the right solution is, but maybe a combination of

1) postgresql-common at least "suggests" ca-certificates.
2) apt.postgresql.org.sh should do more checking that the setup it
creates actually works.
3) The wiki page quickstart makes more explicit mention of
ca-certificates. (It is mentioned for the manual setup.)
