You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: db_version_file.go
    path of file: ./repos/steampipe/pkg/ociinstaller/versionfile
    
    the code of the file until where you have to start completion: package versionfile

import (
	"encoding/json"
	"log"
	"os"
	"time"

	filehelpers "github.com/turbot/go-kit/files"
	"github.com/turbot/steampipe/pkg/filepaths"
)

const DatabaseStructVersion = 20220411

type DatabaseVersionFile struct {
	FdwExtension  Inst
    
func readDatabaseVersionFile(path string) (*DatabaseVersionFile, error) {
	file, _ := os.ReadFile(path)
	var data DatabaseVersionFile
	if err := json.Unmarshal(file, &data); err != nil {
		log.Println("[ERROR]", "Error while reading DB version file", err)
		return nil, err
	}
	if data.FdwExtension == (InstalledVersion{}) {
		data.FdwExtension = InstalledVersion{}
	}

	if data.EmbeddedDB == (InstalledVersion{}) {
		data.EmbeddedDB = InstalledVersion{}
	}

	return &data, nil
}
