# Solution: Dockerfile with PostgreSQL Client Tools for Module 8
# This Dockerfile extends the production-ready Dockerfile from Module 7
# to include PostgreSQL client tools (pg_dump, psql) needed for backup/restore functionality
#
# Use this Dockerfile if your operator performs backups/restores using pg_dump/psql
