Binder Error: No function matches the given name and argument types 'json_extract(JSON, BOOLEAN)'.

MCVE in Snowflake:

CREATE OR REPLACE TEMPORARY TABLE TBL (COL OBJECT);
INSERT INTO TBL (COL) SELECT ({'K1': {'K2': 1}});

-- 1 row
SELECT * FROM TBL;

-- 1 row
SELECT COL
FROM TBL
WHERE COL:K1:K2 > 0;

MCVE failing wih fakesnow:

import fakesnow
import snowflake.connector


def main():
    with fakesnow.patch():
        conn = snowflake.connector.connect(database="X", schema="Y")
        conn.execute_string("CREATE TEMPORARY TABLE TBL (COL OBJECT)")
        conn.execute_string("INSERT INTO TBL (COL) SELECT ({'K1': {'K2': 1}})")
        row = conn.cursor().execute("SELECT * FROM TBL").fetchone()
        assert row[0] == '{"K1":{"K2":1}}'
        sql = """

Thanks for the very clear repro! I've raised duckdb/duckdb#10786 and will look into a work-around in the meantime.
