### Purpose A filtered query over a catalog-managed format table still lists every partition. This PR derives a conservative partition name pattern from equality and bounded range predicates on leading partition fields, and passes it to the paged partition listing. A predicate that cannot be represented safely falls back to the unfiltered listing, so no matching partition can be dropped. String prefixes are computed by Unicode code point, so a generated pattern never contains an isolated surrogate. ### Tests `PartitionNamePatternsTest` and `CatalogFormatTablePartitionManagerTest` cover equality and range combinations, unsupported predicates, null boundaries, escaping, Unicode supplementary characters, and the manager integration. -- This is an automated message from the Apache Git Service.
