Few initial comments:
=====================
1.
+ relreplindex = relation->rd_replidindex;
+
+ /*
+ * build attributes to idindexattrs.
+ */
+ idindexattrs = NULL;
+ foreach(l, indexoidlist)
+ {
+ Oid indexOid = lfirst_oid(l);
+ Relation indexDesc;
+ int i;
+ bool isIDKey; /* replica identity index */
+
+ indexDesc = RelationIdGetRelation(indexOid);

When you have oid of replica identity index (relreplindex) then what
is the need to traverse all the indexes?

2.
It is better to name the function as RelationGet...
