**Describe the bug** <!-- A clear and concise description of what the bug is. --> Related to DataFusion issues: * https://github.com/apache/arrow-datafusion/issues/3479 * https://github.com/apache/arrow-datafusion/issues/3487 **To Reproduce** <!-- Steps to reproduce the behavior: --> ```sql ❯ select null + 1::decimal; Plan("'Null + Decimal128(38, 10)' can't be evaluated because there isn't a common type to coerce the types to") ❯ select a < null from (values (1.1::decimal)) as t(a); ArrowError(ExternalError(Internal("Cannot convert Decimal128(None,38,10) to i128"))) ``` **Expected behavior** <!-- A clear and concise description of what you expected to happen. --> Expect them to behave like other numerics, where mathematical and comparison operators function correctly when given nulls. ```sql ❯ select null + 1; +-----------------+ | NULL + Int64(1) | +-----------------+ | | +-----------------+ 1 row in set. Query took 0.002 seconds. ❯ select null < 1.1::decimal; +---------------------+ | NULL < Float64(1.1) | +---------------------+ | | +---------------------+ 1 row in set. Query took 0.002 seconds. ``` **Additional context** <!-- Add any other context about the problem here. --> -- This is an automated message from the Apache Git Service.
