## What is the purpose of the change If the current catalog is unreachable, any SQL query fails to parse - even queries that make fully-qualified accesses to catalogs that are reachable. This is because we make a call to databaseExists in the current catalog as part of parsing the statement. ## Brief change log This commit wraps the call to databaseExists in a try..catch so it doesn't block the remainder of the parsing. ## Verifying this change This change added tests and can be verified as follows: - Added unit tests - Manually verified using the attached recreate: [flink-catalog-repro.zip](https://github.com/user-attachments/files/30140283/flink-catalog-repro.zip) ## Does this pull request potentially affect one of the following parts: - Dependencies (does it add or upgrade a dependency): no - The public API, i.e., is any changed class annotated with `@Public(Evolving)`: no - The serializers: no - The runtime per-record code paths (performance sensitive): no - Anything that affects deployment or recovery: JobManager (and its components), Checkpointing, Kubernetes/Yarn, ZooKeeper: no - The S3 file system connector: no ## Documentation - Does this pull request introduce a new feature? no - If yes, how is the feature documented? not applicable --- ##### Was generative AI tooling used to co-author this PR? - [X] Yes Generated-by: Claude Sonnet 5 -- This is an automated message from the Apache Git Service.
