…ostgres compatible (apache#20499) ## Which issue does this PR close? <!-- We generally require a GitHub issue to be filed for all bug fixes and enhancements and this helps us generate change logs for our releases. You can link an issue to this PR using the GitHub syntax. For example `Closes apache#123` indicates that this PR will close issue apache#123. --> - Closes apache#20502 ## Rationale for this change The following query is failing with the following error: `SELECT date_bin(NULL, TIMESTAMP '2023-01-01 12:30:00', TIMESTAMP '2023-01-01 12:00:00') ` `Error: Error during planning: Failed to coerce arguments to satisfy a call to 'date_bin' function: coercion from Null, Timestamp(ns), Timestamp(ns) to the signature OneOf([....])` ## What changes are included in this PR? Fix `date_bin(NULL, ...)` to return `NULL` instead of a planning error by allowing Nulls to coerce to Interva. ## Are these changes tested? I added a sqllogictest case to verify the query executes and returns `NULL`. ## Are there any user-facing changes? <!-- If there are user-facing changes then we may require documentation to be updated before approving the PR. --> <!-- If there are any breaking changes to public APIs, please add the `api change` label. --> Yes, previously `date_bin(NULL, ...) `returned a planning error. It now returns NULL. (cherry picked from commit e937cad)
