-- kham_pg--0.8.0--0.8.1.sql
--
-- Upgrade path: 0.8.0 → 0.8.1
--
-- No SQL object changes in this release.  The 0.8.1 update is a performance-
-- only fix in the Rust extension binary:
--
--   * OnceLock-cached parser FtsTokenizer (eliminates 46.7 ms init per call)
--   * Single contiguous text_buf in KhamState (O(n) → O(1) allocations/doc)
--   * Per-word LRU lexeme cache in kham_dict_lexize (4096 entries/algorithm)
--
-- Running ALTER EXTENSION kham_pg UPDATE loads the new .so automatically.
-- No DDL changes are required.
