-- pg_tre 3.2.5 -> 3.2.6 upgrade.
--
-- No catalog changes.  3.2.6 fixes a page leak: a pending-list merge
-- (VACUUM) consumed its pages without ever freeing them, so an index under
-- steady insert traffic grew without bound until REINDEX.  Storage-layer
-- only; `diff sql/pg_tre--3.2.5.sql sql/pg_tre--3.2.6.sql` differs only in
-- the header comment.
--
-- No on-disk format change and NO REINDEX required.  Already-leaked pages
-- from earlier versions are not retroactively reclaimed (nothing records
-- which blocks they were); the next merge stops adding to the pile, and a
-- REINDEX reclaims the historical waste if you want the space back.
