    • To start the PostgreSQL database, run:

      Copy 
      # su -tns -c "/opt/sc/support/bin/pg_ctl -D opt/sc/data/postgresql/ -l /opt/sc/admin/logs/postgresql.log start"

    • To stop the PostgreSQL database, run:

      Copy 
      # su -tns -c "/opt/sc/support/bin/pg_ctl -D opt/sc/data/postgresql/ stop"

    Note: These commands assume the install path for the PostgreSQL database is /opt/sc/. Replace /opt/sc/ with your install path if necessary. For more information about managed PostgreSQL databases, see Connect an External PostgreSQL Server.
