### What changes were proposed in this pull request? Add another fallback for broken (non-resolved) exists_default values for SPARK-51119 original fix. ### Why are the changes needed? https://github.com/apache/spark/pull/49962 added a fallback in case there were already broken (ie, non-resolved) persisted default values in catalogs. A broken one is something like 'current_database, current_user, current_timestamp' , these are non-deterministic and will bring wrong results in EXISTS_DEFAULT, where user expects the value resolved when they set the default. However, this fallback missed one case when the current_xxx is in a cast. This fixes it. ### Does this PR introduce _any_ user-facing change? No ### How was this patch tested? Add to existing unit test in StructTyepSuite ### Was this patch authored or co-authored using generative AI tooling? No -- This is an automated message from the Apache Git Service.
