Why do you think --filter pod= is valid? Our documentation mentions these filters: https://github.com/containers/podman/blob/master/docs/source/markdown/podman-ps.1.md#--filter--f

Labelling this as feature request for pod filter support

Concur, this looks like an RFE. It seems like a good filter to add, though.
