Sorry for continuously disturbing in this topic, but am I missing something here?

I mean that in case of type's OID in PUBLICATION host does not exists in SUBSCRIPTION host's pg_type,
it could returns unintended error (the XX000 above) when elog or ereport is executed.

For more details, it happen in slot_store_error_callback when it try to call format_type_be(localtypoid) for
errcontext.
slot_store_error_callback is set in slot_store_cstrings, slot_modify_cstrings function and it also be unset here, so
theeffect here is small but it happens.
