One of the files generated by the /opt/vertica/scripts/collect_diag_dump.sh script details the raw and compressed size for every table in the Vertica database.

At the bottom of the report there is a “total” line that shows the database raw and compressed size!

Example:

[[email protected] ~]$ /opt/vertica/scripts/collect_diag_dump.sh -c -s false
Database Password:
Exporting profiling data........ Done
Exporting catalog and design.. Done
