-- pg_turbovec 1.27.2
--
-- Build-time-only change: IVF k-means reservoir sampling now defers the
-- O(dim^2) per-row rotation to only the rows kept in the reservoir
-- (<= 256*lists), instead of rotating all N accepted rows. On-disk
-- index format is byte-identical to 1.27.1 (same trained centroids,
-- same codes). No wire change, no SQL surface change, no REINDEX.
--
-- `ALTER EXTENSION pg_turbovec UPDATE TO '1.27.2';` is sufficient.
