I guess it's a bit late at this point, but in theory keeping the same
List-Id headers as before may help with how many people have to
change their filters.
Using lists.postgresql.org as the new domain was explained
in the announce, but it's not clear why List-Id had to follow
the other List-* fields.
Unless it was the reason mentioned in the last sentence below.

Quoting RFC-2919:

4. Persistence of List Identifiers

Although the list identifier MAY be changed by the mailing list
administrator this is not desirable. (Note that there is no
disadvantage to changing the description portion of the List-Id
header.) A MUA may not recognize the change to the list identifier
because the MUA SHOULD treat a different list identifier as a
different list. As such the mailing list administrator SHOULD avoid
changing the list identifier even when the host serving the list
changes. On the other hand, transitioning from an informal
unmanaged-list-id-namespace to a domain namespace is an
acceptable reason to change the list identifier.
