beliefer opened a new pull request #35999: URL: https://github.com/apache/spark/pull/35999
### What changes were proposed in this pull request? DS V2 supports push down CAST to database. The current implement only uses the typeName of DataType. For example: `Cast(column, StringType)` will be build to `CAST(column AS String)`. But it should be `CAST(column AS TEXT)` for Postgres or `CAST(column AS VARCHAR2(255))` for Oracle. ### Why are the changes needed? Improve the implement of push down CAST. ### Does this PR introduce _any_ user-facing change? 'No'. Just new feature. ### How was this patch tested?
