COMMENT ON FUNCTION pg_tre_index_tid_packing(regclass) IS
    'How the index packs heap TIDs: ''dense'' (built by pg_tre 4.4.0 or '
    'later on a heap table) or ''legacy'' (built by an earlier version, '
    'or on another table access method).  A legacy index works '
    'unchanged; REINDEX rebuilds it dense, typically 2-2.5x smaller on '
    'long-text columns.';
