• Port information

• SSL/TLS certificates (if applicable)

Example connection string:

postgresql://username:password@hostname:port/database

Best Practices

1. Security

   • Use private visibility when possible

   • Implement strong passwords

   • Regularly rotate credentials

   • Limit network access

   • Use SSL/TLS encryption

2. Performance

   • Monitor resource utilization

   • Choose appropriate instance type

   • Regular VACUUM operations

   • Proper indexing strategy

   • Connection pooling

3. Backup

   • Enable automated backups

   • Test restore procedures

   • Keep backup window during low-traffic periods

   • Maintain backup copies

   • Verify WAL archiving

Troubleshooting

Common issues and solutions:

1. Connection Issues

   • Verify network access

   • Check credentials

   • Confirm port accessibility

   • Validate SSL/TLS settings

   • Review pg_hba.conf

2. Performance Problems

   • Monitor resource metrics

   • Check slow queries

   • Review index usage

   • Analyze query plans

   • Check for bloat

3. Backup Failures

   • Verify storage space

   • Check backup user permissions

   • Review backup logs

   • Validate backup configuration

   • Check WAL settings
