The SQL:2011 standard does describe a mechanism for solving this called System Versioned Tables, but the only database I've encountered that implements it so far is MariaDB: https://mariadb.com/kb/en/system-versioned-tables/

https://en.wikipedia.org/wiki/Temporal_database lists a few more - apparently there are versions of this in Oracle, DB2 and SQL Server now.



I happened to fall down this rabbit hole a few days ago because of another HN thread. In it, a commenter mentioned [1] a talk by Markus Winand where he goes over some of the more interesting additions to the SQL standard since 92, including versioned tables [2] (I've linked to the timestamp, but the whole talk is good).

I got real excited about that feature because I could think of a few tables at work that could use it. Sadly, PostgreSQL doesn't implement it [3] (I can't permalink to the feature but you can search for "T180", "System-versioned tables", "T181", or "Application-time period tables").
