in pg_stats_vacuum
if (type == PGSTAT_EXTVAC_INDEX || type == PGSTAT_EXTVAC_HEAP)
{
Oid relid = PG_GETARG_OID(1);

/* Load table statistics for specified database. */
if (OidIsValid(relid))
{
tabentry = fetch_dbstat_tabentry(dbid, relid);
if (tabentry == NULL || tabentry->vacuum_ext.type != type)
/* Table don't exists or isn't an heap relation. */
PG_RETURN_NULL();

tuplestore_put_for_relation(relid, rsinfo, tabentry);
}
else
{
}

So for functions pg_stat_vacuum_indexes and pg_stat_vacuum_tables,
it seems you didn't check "relid" 's relkind,
you may need to use get_rel_relkind.
