PostgreSQL 19 is introducing native support for temporal tables, a long-awaited feature that allows querying historical data states without custom audit triggers. The implementation follows the SQL:2011 standard and provides a more elegant solution compared to the previous approach using exclusion constraints and the btree_gist extension. This addition represents a significant enhancement for applications requiring historical data tracking and temporal queries.
Background
Temporal tables, which track historical changes to data over time, were standardized in SQL:2011 but PostgreSQL has been slow to implement native support. Until now, developers had to use workarounds like custom triggers or exclusion constraints to achieve similar functionality.
