## What is the purpose of the change Add support for reading and writing postgres UUID types via Flink SQL STRING type ## Brief change log - modified AbstractJdbcRowConverter.createInternalConverter to use toString() for CHAR and VARCHAR types instead of casting to string. Previously the cast would fail for postgres UUIDs - add createExternalConverter override to PostgresRowConverter for CHAR and VARCHAR types. It will check if the string is a UUID and pass the UUID to the PreparedSatement via setObject if so ## Verifying this change Please make sure both new and modified tests in this PR follows the conventions defined in our code quality guide: https://flink.apache.org/contributing/code-style-and-quality-common.html#testing *(Please pick either of the following options)* This change is a trivial rework / code cleanup without any test coverage. ## 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 -- This is an automated message from the Apache Git Service.
