Research direction

Start by tracing how PostgreSQL jsonb fields are typed after version 0.0.6 and reproduce the failure when output is sent to target-snowflake. Done means jsonb remains compatible with Snowflake's Variant modeling instead of becoming varchar, avoiding the reported ProgrammingError.
