fix: refactor unsupported DDL handling

CHANGELOG.md

@@ -9,6 +9,7 @@ All notable changes to this project will be documented in this file.
 - sqlfmt no longer adds a space between the function name and parens for `filter()`, `isnull()`, and `rlike('foo', 'bar')` (but it also permits `filter ()`, `isnull ()`, and `rlike ('foo')` to support dialects where those are operators, not function names) ([#641](https://github.com/tconbeer/sqlfmt/issues/641), [#478](https://github.com/tconbeer/sqlfmt/issues/478) - thank you [@williamscs](https://github.com/williamscs), [@hongtron](https://github.com/hongtron), and [@chwiese](https://github.com/chwiese)!).
 - sqlfmt now supports Spark type-hinted numeric literals like `32y` and `+3.2e6bd` and will not introduce a space between the digits and their type suffix ([#640](https://github.com/tconbeer/sqlfmt/issues/640) - thank you [@ShaneMazur](https://github.com/ShaneMazur)!).
 - sqlfmt now supports Databricks query hint comments like `/*+ COALESCE(3) */` ([#639](https://github.com/tconbeer/sqlfmt/issues/639) - thank you [@wr-atlas](https://github.com/wr-atlas)!).
+- sqlfmt now no-ops instead of errors when encountering `create row access policy` statements with `grant` sub-statements (it also generally more robustly handles unsupported DDL) ([#633](https://github.com/tconbeer/sqlfmt/issues/633)).
