Sandbox Execution ✓

Here are the sandbox execution logs prior to making any changes:

Sandbox passed on the latest main, so sandbox checks will be enabled for this issue.

Step 1: 🔎 Searching

I found the following snippets in your repository. I will now analyze these snippets and come up with a plan.

Step 2: ⌨️ Coding

• Modify ensemble/src/connection.rs ✓ bc87ea1 Edit

Modify ensemble/src/connection.rs with contents:
• Add an optional `role` parameter to the `setup` function. This parameter should be a string that represents the role to be assumed for the session.
• Modify the `get` function to assume the role when a connection is retrieved. This can be done by calling the `assume_role` function on the `Model` trait with the role as a parameter.

• Modify ensemble/src/lib.rs ✓ 22e0ad1 Edit

Modify ensemble/src/lib.rs with contents:
• Add a `assume_role` function to the `Model` trait. This function should take a string parameter that represents the role to be assumed and return a `Result` that indicates whether the operation was successful.
• Modify the `all`, `find`, `create`, and `update` functions to call the `assume_role` function before performing any database operations.

• Create ensemble/src/tests/connection_tests.rs ✓ e48ee80 Edit

Create ensemble/src/tests/connection_tests.rs with contents:
• Add tests for the `setup` function to ensure that it correctly sets up a connection with a role.
• Add tests for the `get` function to ensure that it correctly assumes the role when a connection is retrieved.
• Add tests for the `Model` trait's `assume_role` function to ensure that it correctly assumes a role.

Step 3: 🔁 Code Review

I have finished reviewing the code for completeness. I did not find errors for sweep/postgres-rls-support.

🎉 Latest improvements to Sweep:

• We just released a dashboard to track Sweep's progress on your issue in real-time, showing every stage of the process – from search to planning and coding.
• Sweep uses OpenAI's latest Assistant API to plan code changes and modify code! This is 3x faster and significantly more reliable as it allows Sweep to edit code and validate the changes in tight iterations, the same way as a human would.
