  message:
    storage/innodb_plugin: Relax too strict assertions about prefix
    indexed BLOBs for ROW_FORMAT=DYNAMIC and ROW_FORMAT_COMPRESSED tables
    (Bug #52746). In these tables, the locally stored prefix of a BLOB can
    be as small as 20 bytes (BTR_EXTERN_FIELD_REF_SIZE). ROW_FORMAT=REDUNDANT
    and ROW_FORMAT=COMPACT store a prefix of 768 bytes (REC_MAX_INDEX_COL_LEN).
    
    trx_undo_rec_get_col_val(): Relax the ut_ad() assertion and add a
    reference to dtuple_convert_big_rec().
    
    trx_undo_rec_get_partial_row(): Relax the ut_a() assertion that
    prompted Bug #52746.
