Saturating math

The saturating math hyperfunctions help you perform saturating math on integers. In saturating math, the final result is bounded. If the result of a normal mathematical operation exceeds either the minimum or maximum bound, the result of the corresponding saturating math operation is capped at the bound. For example, 2 + (-3) = -1. But in a saturating math function with a lower bound of zero, the result is 0.

You can use saturating math to make sure your results don't overflow the allowed range of integers, or to force a result to be greater than or equal to zero.

Some hyperfunctions are included in the default TimescaleDB product. For additional hyperfunctions, you need to install the Timescale Toolkit PostgreSQL extension.
