+// PostgreSQL Installer Example
+//
+// This example demonstrates how to use the PostgreSQL installer module to:
+// - Install PostgreSQL using nerdctl
+// - Create a database
+// - Execute SQL scripts
+// - Check if PostgreSQL is running
+//
+// Prerequisites:
+// - nerdctl must be installed and working
+// - Docker images must be accessible
+
+// Define variables
