    Description

      Need to make sure that all statements within TX share the same MVCC version which is assigned on first read/write.
      Need to add tests for this to confirm REPEATABLE_READ behavior.

      Note that regular implicit SELECTs outside transaction should only register itself as "query" on MVCC coordinator, while SELECT inside TX must register itself as both "query" and "tx".
