func main() {
ctx := context.Background()
logger := slog.New(slog.NewTextHandler(os.Stdout, &slog.HandlerOptions{
Level: slog.LevelDebug,
}))

if err != nil {
log.Fatal(err)
}
type User struct {
ID int `json:"id"`

}
hook.OnInsert("users", func(ctx context.Context, e pghook.InsertPayload[User]) error {
fmt.Println("inserted", e.Row)
return nil
})
