Error when running with `read_only=True`

[parkervg]

Hi,

I'm trying to use flock in the code below:

with duckdb.connect(DUCKDB_DB_PATH, read_only=True) as con:
    con.install_extension("flock", repository="community", version=FLOCK_VERSION)
    con.load_extension("flock")

    con.execute(
        """
        CREATE SECRET (
            TYPE OPENAI,
            BASE_URL 'http://localhost:11434/v1',
            API_KEY 'N.A.'
        )
        """
    )

    # Create model configuration
    con.execute(
        f"""
        CREATE MODEL(
            '{MODEL_CONFIG.ollama_model_name}',
            '{MODEL_CONFIG.ollama_model_name}', 
            'openai',
            {{"tuple_format": "JSON", "batch_size": {SYSTEM_PARAMS['batch_size']}, "model_parameters": {{"temperature": {MODEL_PARAMS['temperature']}}}}}
        )
        """
    )

In the con.execute under # Create model configuration, I get the following error:

_duckdb.CatalogException: Catalog Error: Table with name FLOCKMTL_MODEL_USER_DEFINED_INTERNAL_TABLE does not exist!
Did you mean "flock_storage.flock_config.FLOCKMTL_MODEL_USER_DEFINED_INTERNAL_TABLE"?

When I change read_only=False, the error does not occur.
