Interesting. I don't think the "last option wins" model applies to
other pg_dump options, though. For instance, in PG17:
pg_dump --data-only --schema-only
pg_dump: error: options -s/--schema-only and -a/--data-only cannot be
used together
I don't think it's simple to start using "last option wins" behavior
now. There are probably some combinations of options where it's not
clear whether a later option is an extra constraint or will override a
previous option.
