- PostgreSQL Compatibility 12838
- DuckDB's SQL dialect closely follows the conventions of the PostgreSQL dialect. The few exceptions to this are listed on this page. Floating-Point Arithmetic DuckDB and PostgreSQL handle floating-point arithmetic differently for division by
...conforms to the IEEE Standard for Floating-Point Arithmetic (IEEE 754) for both division by zero and operations involving infinity values.
