Also System-Versioned Tables in MariaDB: https://mariadb.com/kb/en/system-versioned-tables/

Oracle has flashback queries (SELECT ... AS OF timestamp).

It's one of these things that are available but most people ignore it and implement it manually with created_at updated_at deleted_at columns etc. I think one reason for this is lack of support in ORMs and lack of standardization between RDBMSes.

Available on postgres as an extension. It's a bit jank and doesn't have language integrated clauses like sql server.
