Invalid Assert while validating REPLICA IDENTITY?

While working on some other code I noticed that in
FindReplTupleInLocalRel() there is an assert [1] that seems to be
passing IndexRelation to GetRelationIdentityOrPK() whereas it should
be passing normal relation.

[1]
if (OidIsValid(localidxoid))
{
#ifdef USE_ASSERT_CHECKING
    Relation idxrel = index_open(localidxoid, AccessShareLock);

    /* Index must be PK, RI, or usable for REPLICA IDENTITY FULL tables */
    Assert(GetRelationIdentityOrPK(idxrel) == localidxoid ||
    IsIndexUsableForReplicaIdentityFull(BuildIndexInfo(idxrel),
    edata->targetRel->attrmap));
    index_close(idxrel, AccessShareLock);
#endif

In the above code, we are passing idxrel to GetRelationIdentityOrPK(),
whereas we should be passing localrel

Fix should be
