Jesse Seldess (jseldess) commented:

PR: cockroachdb/cockroach#62924

From release notes:

The optimizer now folds functions to NULL when the function does not allow NULL arguments and one of the arguments is a NULL constant. As a result, more efficient query plans will be produced for queries with these types of function calls. [#62924][#62924]

Jira Issue: DOC-1340
