Savepoint


In plain English

A savepoint is a bookmark inside a transaction. If something goes wrong after it, you can roll back to the savepoint without throwing away the whole transaction — undoing just the recent part.

Why it matters

Savepoints power “try this, and if it fails handle it” logic inside one transaction. Drivers use them for nested-transaction emulation, but heavy savepoint use adds overhead.
