Few comments:
1. Why do we need to invalidate relsync entries when owner of its
publication changes?
I think the owner change will impact the future Alter Publication ...
Add/Drop/Set/Rename operations as that will be allowed only to new
owner (or super users), otherwise, there shouldn't be an impact on
RelSyncCache entries. Am, I missing something?
2.
+ if (pubform->puballtables)
+ {
+ CacheInvalidateRelSyncAll();
+ }
+ else
+ {
+ List *relids = NIL;
+ List *schemarelids = NIL;
+
+ /*
+ * For partition table, when we insert data, get_rel_sync_entry is
+ * called and a hash entry is created for the corresponding leaf table.
+ * So invalidating the leaf nodes would be sufficient here.
+ */
+ relids = GetPublicationRelations(pubform->oid,
+ PUBLICATION_PART_LEAF);
+ schemarelids = GetAllSchemaPublicationRelations(pubform->oid,
+ PUBLICATION_PART_LEAF);
+
+ relids = list_concat_unique_oid(relids, schemarelids);
+
+ InvalidateRelSyncCaches(relids);
+ }
+
+ CatalogTupleUpdate(rel, &tup->t_self, tup);
Shouldn't we need to update the CatalogTuple before invalidations.
3.

+ schemarelids = GetAllSchemaPublicationRelations(pubform->oid,
+ PUBLICATION_PART_LEAF);
+
+ relids = list_concat_unique_oid(relids, schemarelids);
+
+ InvalidateRelSyncCaches(relids);
+ }
This is a duplicate code. Can we write a function to eliminate this duplicacy?
