$ /opt/PostgreSQL/9.5/bin/pg_dump -U postgres --format=c \
    --file=ahadatamart_pg9.5_2018-01-12.sqlc ahadatamart

Optional: You can also add --table=callsegmentfact before ahadatamart if you only want to back up the callsegmentfact table.

Warning: This takes a while. Mine took around an hour to complete.
