0.16.0 does not contain breaking changes to existing indexes. However, several settings around index creation have been changed.
Please read the changelog carefully.
CREATE INDEX/REINDEX can now leverage Postgres parallel workers, which significantly improves index build times. To fully take advantage
of parallel index builds, some Postgres settings may require tuning. Additionally, the old paradedb.create_index_* and paradedb.statement_* settings have been removed in favor of the built-in
postgresql.conf settings.
Indexing expressions is a new beta feature for advanced users.
