+# Shared PostgreSQL Connection Override for Production
+#
+# This file provides network configuration for connecting to the PostgreSQL Stack.
+# Used by Production Stack.
+#
+# Usage:
+#   Production Stack:
+#     docker compose -f docker-compose.base.yml \
+#                    -f docker-compose.production.yml \
+#                    -f docker-compose.postgres-override.yml up
+#
+# Prerequisites:
+#   - PostgreSQL Stack must be running (creates app-internal network)
+#   - app-internal network must exist as external network
+#   - PostgreSQL Stack: deployment/stacks/postgresql/docker-compose.yml
+
+services:
+  # Production Stack Services
+  # These services will be merged with existing definitions from base.yml + production.yml
