Privacy Detection MMDB sample has different schema than production database

[strobil]

Description

The Privacy Detection sample MMDB file (privacy_detection_sample.mmdb) uses a different data type for boolean fields compared to the production database downloaded from IPinfo.

Problem

In the sample file, boolean fields (hosting, proxy, tor, relay, vpn) are stored as strings ("true" / "false").

In the production database, the same fields are stored as native booleans (true / false).

Reproduction

// Sample file - requires string type
type record struct {
    Hosting string `maxminddb:"hosting"` // works: Hosting="true"
}

// Production file - requires bool type  
type record struct {
    Hosting bool `maxminddb:"hosting"` // works: Hosting=true
}

Attempting to use bool type with the sample file results in:

maxminddb: cannot unmarshal true (string) into type bool

Attempting to use string type with the production file results in:

maxminddb: cannot unmarshal true (bool) into type string

Expected Behavior

Sample and production databases should have identical schemas to allow proper integration testing.

main.go

package main

import (
	"fmt"
	"net/netip"

	"github.com/oschwald/maxminddb-golang/v2"
)

type recordBool struct {
	Hosting bool   `maxminddb:"hosting"`
	Proxy   bool   `maxminddb:"proxy"`
	Tor     bool   `maxminddb:"tor"`
	Relay   bool   `maxminddb:"relay"`
	VPN     bool   `maxminddb:"vpn"`
	Service string `maxminddb:"service"`
}

func main() {
	reader, err := maxminddb.Open("privacy_detection_sample.mmdb")
	if err != nil {
		panic(err)
	}
	defer reader.Close()

	ip := netip.MustParseAddr("1.0.0.0")

	var record recordBool
	err = reader.Lookup(ip).Decode(&record)
	if err != nil {
		fmt.Println("Error:", err)
		// Output: Error: at offset 0, path /hosting: maxminddb: cannot unmarshal true (string) into type bool
		return
	}

	fmt.Printf("Hosting: %v, VPN: %v\n", record.Hosting, record.VPN)
}
