Inconsistent synchronization around odbc sync handling

    Details

      Description

      There is a narrow race condition when an odbc message is followed by sync - the isExecuting check is supposed to prevent the sync until the execution is complete, but is not synchronized.

      The result can be an exception in the pg client:

      java.lang.IndexOutOfBoundsException: Index: 0, Size: 0
      at java.util.ArrayList.rangeCheck(ArrayList.java:653)
      at java.util.ArrayList.get(ArrayList.java:429)
      at org.postgresql.core.v3.QueryExecutorImpl.processResults(QueryExecutorImpl.java:1825)
      at org.postgresql.core.v3.QueryExecutorImpl.execute(QueryExecutorImpl.java:255)

      As the pendingExecuteQueue will have been cleared by the early response to sync.
