dbms_redefinition is a Halo/PostgreSQL extension which lets you make schema changes to tables and indexes. Unlike ALTER TABLE, it works online, without holding a long lived exclusive lock on the processed tables during the migration. It builds a copy of the target table and swaps them.

The work based on the excellent pg_migrate (https://github.com/phillbaker/pg_migrate) & pg_repack project (https://reorg.github.io/pg_repack).
