Looking Forward to Postgres 19: It's About Time

Postgres 19 is introducing native temporal table support, finally implementing a feature formalized in the SQL:2011 standard over a decade ago that allows users to track how data looked at specific past dates. Previously, Postgres required developers to manually implement temporal tracking using the btree_gist extension and exclusion constraints, which was complex and unintuitive. The new native support addresses longstanding demands in the Postgres community for proper temporal data management.
