January 2026 (2026-01) monthly summary for typeorm/typeorm. Key features delivered: - PostgreSQL driver extensions auto-install: Added the ability to specify and automatically install additional PostgreSQL extensions when establishing a connection, enhancing database functionality and driver flexibility. (Commit: fbb625b40322ccf5fad1dade56ad843b6d430740) - QueryBuilder data manipulation enhancements: Implemented INSERT INTO ... SELECT FROM ... and improved upsert SQL generation with proper table aliases to enable richer data manipulation patterns. (Commits: 8fc091529a176ec9d0a8a613725f9044809bcfce; 42ce6300f6cc6f1c7aacb3151e7685e95971cff7) - PostgreSQL geometry types support: Enhanced handling of geometry types (point and circle) with string and object inputs; introduced a GeometryEntity for testing and fixed re-save edge cases. (Commit: 65dea3c0f562203fa729d1bed2775c11efa21845) - SQLite enum arrays handling improvements: Improves conversion between enums and strings for simple-enum arrays and adds parsing utilities to ensure correctness. (Commit: 73227bc88e5acf700f4df6f9c7632912ad02d58c) - Testing and quality improvements for ORM and SQL generation: Expanded tests and checks for unique constraints, composite relations, embedded entities, synchronization with multiple foreign keys, JSONB operators, and relation IDs in embedded entities. (Commits: db2369c41108d878e4f9c0f861e95612869568a0; b0dd92d373dbac9af05c81ede0bc7ba5372559e0; 13ab7c360610c6d34af96b914d1027ceb3e24763; a0d190d82fb4555a156ba0722a25656b43c8b1fd; ed2478a403a7b97e5102f9b32e2c162096710011; 5237beebff42b3898cf87638048986e6565542bd) Major bugs fixed: - Fix: handle re-save of postgres geometric types (#11857) - Fix: sqlite simple-enum arrays correctly (#11865) - Fix: raw select query with correctly ordered selected columns (#11902) - Fix: ON CONFLICT ON CONSTRAINT tests updated (#11908) - Fix: handle relation ids in nested embedded entities (#11942) Overall impact and accomplishments: - The month delivered significant business value by widening database extension support, enabling richer SQL patterns, and raising correctness and reliability across PostgreSQL and SQLite usage. Strengthened test coverage reduces regression risk and accelerates future releases. Technologies/skills demonstrated: - PostgreSQL and SQLite driver work, advanced SQL generation, QueryBuilder enhancements, geometry and enum handling, embedded/relational modeling, JSONB operators, and comprehensive test automation.
