  "message": "Add missing conditional functions (#1464)\n\n* Add missing conditional functions: greatest, least, nvl2, ifnull (#1449)\n\nExpose four conditional functions from upstream DataFusion that were\nnot yet available in the Python bindings.\n\nCo-Authored-By: Claude Opus 4.6 (1M context) \u003cnoreply@anthropic.com\u003e\n\n* Add unit tests for greatest, least, nvl2, and ifnull functions\n\nTests cover multiple data types (integers, strings), null handling\n(all-null, partial-null), multiple arguments, and ifnull/nvl equivalence.\n\nCo-Authored-By: Claude Opus 4.6 (1M context) \u003cnoreply@anthropic.com\u003e\n\n* Use standard alias docstring pattern for ifnull\n\nCo-Authored-By: Claude Opus 4.6 (1M context) \u003cnoreply@anthropic.com\u003e\n\n* remove unused df fixture and fix parameter shadowing\n\n* Refactor conditional function tests into parametrized test suite\n\nReplace separate test functions for coalesce, greatest, least, nvl,\nnvl2, ifnull with a single parametrized test using a shared fixture.\nAdds coverage for nvl, nullif (previously untested), datetime and\nboolean types, literal fallbacks, and variadic calls.\n\nCo-Authored-By: Claude Opus 4.6 (1M context) \u003cnoreply@anthropic.com\u003e\n\n---------\n\nCo-authored-by: Claude Opus 4.6 (1M context) \u003cnoreply@anthropic.com\u003e",
