Utility for Greenplum Database that performs a table integrity exam to verify that all the tables in a specific database can be queried.
The purpose of this tool is to detect when any of the segments in Greenplum have a bad copy of a table file(s). This is an issue that can happen when there is disk corruption in any of the nodes of the cluster and a disk repair utility is ran (i.e. xfs_repair, fsck)
This tool will go through each and every table of a specific database and perform a PostgreSQL COPY command to /dev/null in all segments to verify the table can be queried in the whole cluster.
COPY example_table TO '/dev/null'
