PostgreSQL: pgclone 4.0.0 released

pgclone 4.0.0 is a new PostgreSQL extension that enables native SQL-based cloning of databases, schemas, and tables without relying on pg_dump, pg_restore, or shell scripts. It uses the PostgreSQL COPY protocol and custom Background Workers for high-performance parallel cloning. Key features include integrated data masking (emails, names, phone numbers) with auto-discovery of sensitive columns, full DDL support (indexes, constraints, triggers, views, sequences), flexible conflict resolution strategies, and compatibility with PostgreSQL 14 through 18. Released under the PostgreSQL Licence.
