Thanks for updating the patch.
Here are a few comments.

1)
+ *        ALL TABLES IN SCHEMA schema [[, ...]

[[ -> [

2)
+    /* ALTER PUBLICATION ... ADD/DROP TABLE/ALL TABLES IN SCHEMA parameters */

The two '/' seems a bit unclear and it doesn't mention the SET case.
Maybe we can write like:

/* parameters used for ALTER PUBLICATION ... ADD/DROP/SET publication objects */

3)
+    /*
+     * Check if setting the relation to a different schema will result in the
+     * publication having schema and same schema's table in the publication.
+     */
+    if (stmt->objectType == OBJECT_TABLE)
+    {
+        ListCell   *lc;
+        List       *schemaPubids = GetSchemaPublications(nspOid);
+        foreach(lc, schemaPubids)
+        {
+            Oid        pubid = lfirst_oid(lc);
+            if (list_member_oid(GetPublicationRelations(pubid, PUBLICATION_PART_ALL),
+                                relid))
+                ereport(ERROR,

How about we check this case like the following ?

List       *schemaPubids = GetSchemaPublications(nspOid);
List       *relPubids = GetRelationPublications(RelationGetRelid(rel));
if (list_intersection(schemaPubids, relPubids))
    ereport(ERROR, ...

Best regards,
