Covers Postgres 17 (Sept 2024) incremental backup, JSON_TABLE, and MERGE improvements, Postgres 18 (Sept 2025) virtual generated columns and OAuth2, the vector extension lineage of pgvector / pgvectorscale / pgvector.rs / pgai, domain extensions TimescaleDB / PostGIS / pgRouting, PgBouncer / Pgpool-II connection pooling, the distributed/cloud options Citus / Hydra / Tembo / Crunchy Data, the operational extensions pglogical / pg_partman / pg_cron / pg_repack / pg_stat_statements, pgmustard and Postgres.ai for AI-assisted query plans, pgBackRest / Barman / WAL-G for backups, plus case studies from Toss, Kakao, NAVER, Mercari, and the NTT Postgres committers.
