-- pg_tre 3.2.4 -> 3.2.5 upgrade.
--
-- No catalog changes.  3.2.5 fixes a regex-tokenizer bug: a literal '-'
-- first or last in a bracket expression (`[-_.]`, `[abc-]`, `[-]`,
-- `[^-x]` -- all valid POSIX) was rejected with "invalid regex pattern"
-- instead of matching.  Scan-path only; `diff sql/pg_tre--3.2.4.sql
-- sql/pg_tre--3.2.5.sql` differs only in the header comment.
--
-- No on-disk format change and NO REINDEX required.  Patterns that
-- previously ERRORed simply start working once the new .so is loaded.
