No, I don't think so --- this documentation matches the actual code,
in bufpage.h:

    ...
    LocationIndex pd_lower;        /* offset to start of free space */
    LocationIndex pd_upper;        /* offset to end of free space */
    LocationIndex pd_special;      /* offset to start of special space */
    uint16        pd_pagesize_version;
    TransactionId pd_prune_xid;    /* oldest prunable XID, or zero if none */
    ItemIdData    pd_linp[FLEXIBLE_ARRAY_MEMBER]; /* line pointer array */
    ...
