Security Features PostgreSQL 18 introduces oauth authentication, which lets users authenticate using OAuth 2.0 mechanisms supported through PostgreSQL extensions. Additionally, PostgreSQL 18 adds several features to validate and enforce FIPS mode behavior, and also adds the ssl_tls13_ciphers to let users configure which TLS v1.3 cipher suites the server can use. This release deprecates md5 password authentication in favor of using SCRAM authentication that was first added in PostgreSQL 10. md5 authentication will be fully removed in a future major version release. Additionally, PostgreSQL 18 adds support for SCRAM passthrough authentication with both postgres_fdw and dblink when authenticating to remote PostgreSQL instances.
PostgreSQL, the open source database that continues to get better, is introducing oauth support. This should help with database automation and hopefully bring us one step closer to moving away from static credentials and copying usernames and passwords around. www.postgresql.org/about/news/p...
