// Initialize custom config
store := postgres.New(postgres.Config{
	Host:            "127.0.0.1",
	Port:            5432,
	Database:        "fiber",
	Table:           "fiber_storage",
	Clear:           false,
	GCInterval:      10 * time.Second,
})
```

### Config

// Config defines the config for storage.
type Config struct {
	// Host name where the DB is hosted
