There is one more case that user-defined data type is not supported in Logical Replication.
That is when remote data type's name does not exist in SUBSCRIBE.

In relation.c:logicalrep_typmap_gettypname
We search OID in syscache by remote's data type name and mapping it, if it does not exist in syscache 
We will be faced with the bellow error.

    if (!OidIsValid(entry->typoid))
        ereport(ERROR,
                (errcode(ERRCODE_OBJECT_NOT_IN_PREREQUISITE_STATE),
                 errmsg("data type \"%s.%s\" required for logical replication does not exist",
                        entry->nspname, entry->typname)));

I think, it is not necessary to check typoid here in order to avoid above case, is that right?
I attached a patch based on Sawada-san's patch with a bit of messages modified and remove the above check.
Could somebody check it for me or should I add it into CF?
