Resolved Issues in Greenplum Database 4.3.7.1

In some cases, Greenplum Database utility gpcrondump performance was poor because the utility was performing checks for database metadata, such as indexes and triggers, on both the Greenplum Database segments and the master. Performance has been improved by not performing the checks on the segments.
