PSA a patch to change this message text. The message now has wording
similar to the suggestion.

The name/list substitution is now done within parentheses, which AFAIK
will be enough to eliminate any translation ambiguities.

Right, IIUC that was the reason for not choosing to show the tables in
the original patch -- i.e. the list might easily be very long with
100s or 1000s of tables it, and so inappropriate to substitute in the
message. OTOH, showing only problematic publications is a short list
but it is still more useful than showing nothing (e.g. there other
publications of the subscription might be OK so those ones are not
listed)
