Description: DO188 Section 2.3 leaves out something important
When discussion the podman network connect command, section 2.3 says this:

and this:

However, when this is done, an error occurs (I'm using a live RHEL 9.2 system with Podman 4.4.1 and real images and containers):

What the text of the section fails to mention is that the container must already be connected to a network (other than the default podman network) before podman network connect can connect it to another one. (This point, incidentally, is made in the containers chapter [13] in RH134).

So, to make it work:

I removed the container (The WARN message was simply because I'd used a sleep infinity command in the container to prevent it from exiting.)
I recreated the contaner, connecting it a network (postgres-net).
Then I used the podman network connect command to connect it to the example-net network.
Voilà!
