Go Hood saving to Postgres, but not sure where

I have a SaveRequest method that takes and http.Request and then, supposedly, saves it (right now just the path) to a postgres database:

func (logger *PostgresLogger) SaveRequest(req *http.Request) {
  os.Stdout.Write([]byte("Saving to PGDB\n"))
  request := db.Requests { Path: req.URL.Path }
  transaction := logger.dbConnection.Begin()
  Id, saveError := transaction.Save(&request)
  if saveError != nil {
    panic(saveError)
  }

  os.Stdout.Write([]byte(fmt.Sprintf("%v\n", Id)))

  transactionError := logger.dbConnection.Commit()
  if transactionError != nil {
    panic(transactionError)
  }
}

That dbConnection comes from loading a Hood config file:

func New(prefix string) (PostgresLogger) {
  dbConnection, err := hood.Load("/Users/ls/Dropbox/programming/go/src/postgres_logger/db/config.json", "development")
  if err != nil {
    panic(err)
  }

  return PostgresLogger{ prefix: prefix, dbConnection: dbConnection }
}

Cool. So when I start the reverse proxy and ask it to save incoming requests, I see this (sample, where logs are prefixed by RVSPRXY):

Saving to PGDB

[::1]:51143 GET /js/handlebars.min.js

Saving to PGDB

[::1]:51144 GET /js/jquery-2.0.0.min.js

Saving to PGDB

59
60

So we can see it incrementing the id being returned from Save, but I look in the logging_development database and there are no records.

Stopping and restarting the server continues to increment the ids from where it left off, so it seems like it is actually saving, but where?

Update

Here is the development config:

{
   "development": {
     "driver": "postgres",
     "source": "user=logging dbname=logging_development sslmode=disable"
   }
 }

And some of what PGAdmin shows for connections:

5289	logging	logging_development	2013-05-11 17:54:48.700467-06	127.0.0.1:51403	INSERT INTO "requests" ("path", "created_at", "updated_at") VALUES ($1, $2, $3) RETURNING "id"

5293	logging	logging_development	2013-05-11 17:54:48.74866-06	

Edit: fixed a bug checking the wrong error (not the cause of the issue)

You wrote:

func (logger *PostgresLogger) SaveRequest(req *http.Request) {
	os.Stdout.Write([]byte("Saving to PGDB\n"))
	request := db.Requests{Path: req.URL.Path}
	transaction := logger.dbConnection.Begin()
	Id, saveError := transaction.Save(&request)
	if saveError != nil {
		panic(saveError)
	}
	os.Stdout.Write([]byte(fmt.Sprintf("%v\n", Id)))
	transactionError := logger.dbConnection.Commit()
	if saveError != nil {
		panic(transactionError)
	}
}

What results do you get if you write:

func (logger *PostgresLogger) SaveRequest(req *http.Request) {
	os.Stdout.Write([]byte("Saving to PGDB\n"))
	request := db.Requests{Path: req.URL.Path}
	transaction := logger.dbConnection.Begin()
	Id, saveError := transaction.Save(&request)
	if saveError != nil {
		panic(saveError)
	}
	os.Stdout.Write([]byte(fmt.Sprintf("%v\n", Id)))
	// commit transaction
	transactionError := transaction.Commit()
	// check transactionError
	if transactionError != nil {
		panic(transactionError)
	}
}
