The current tests would diff on the SELECT queries containing ORDER BY
LIMIT on a gpdemo cluster (seen on my MacOS Mojave laptop and on a
CentOS 6 & 7 VM). Most likely the test answer file was created from a
cluster that was not the test standard 3 primary segment configuration
so the SELECT may output differently.
