Thanks for the updated patch.
Few minor comments:
1) The extra line break after IsIndexOnlyOnExpression function can be removed:
+ }
+
+ return true;
+}
+
+
+/*
+ * Returns true if the attrmap (which belongs to remoterel) contains the
+ * leftmost column of the index.
+ *
+ * Otherwise returns false.
+ */

2) Generally we don't terminate with "." for single line comments
+
+ /*
+ * Simple case, we already have a primary key or a replica identity index.
+ */
+ idxoid = GetRelationIdentityOrPK(localrel);
+ if (OidIsValid(idxoid))
+ return idxoid;
