+
+GoNavi 的 Linux 二进制依赖系统 WebKitGTK 运行库。不同发行版默认版本不同：
+
+- Debian 13 / Ubuntu 24.04 及更新版本：通常为 WebKitGTK 4.1
+- Ubuntu 22.04 / Debian 12 等：通常为 WebKitGTK 4.0
+
+如果启动时报错（如 `libwebkit2gtk-4.0.so.37: cannot open shared object file`），请按系统安装对应依赖后重试：
+
+```bash
+# Debian 13 / Ubuntu 24.04+
+sudo apt-get update
+sudo apt-get install -y libgtk-3-0 libwebkit2gtk-4.1-0 libjavascriptcoregtk-4.1-0

+sudo apt-get update
+sudo apt-get install -y libgtk-3-0 libwebkit2gtk-4.0-37 libjavascriptcoregtk-4.0-18
+```
+
+如果你使用的是 Release 中带 `-WebKit41` 后缀的 Linux 产物，请优先在 Debian 13 / Ubuntu 24.04+ 上使用；普通 Linux 产物更适合 WebKitGTK 4.0 运行环境。

-# HighGo 可选代码优化建议
-
-## 一、sslmode 配置优化
-
-### 当前状态
-
-**文件**：`internal/db/highgo_impl.go:43`
-
-**当前代码**：
-```go
-q.Set("sslmode", "disable")
-```
-
-### 建议修改
-
-根据瀚高官方文档，sslmode 的默认值应该是 `require`。建议修改为：
-
-```go
-q.Set("sslmode", "require")
-```
-
-### 修改原因
-
-1. **符合官方规范**：瀚高官方文档明确指出默认 sslmode 为 `require`
-2. **安全性提升**：启用 SSL 加密可以保护数据传输安全
-3. **生产环境最佳实践**：生产环境应该启用 SSL 连接
-
-### 是否需要修改？
-
-**不一定需要修改**，取决于您的实际环境：
-
-#### 保持 `disable` 的场景：
-- ✅ 开发/测试环境
-- ✅ HighGo 服务器未配置 SSL 证书
-- ✅ 内网环境，不需要加密传输
-- ✅ 快速测试连接功能
-
-#### 修改为 `require` 的场景：
-- ✅ 生产环境
-- ✅ HighGo 服务器已配置 SSL 证书
-- ✅ 跨网络连接，需要加密保护
-- ✅ 符合安全合规要求
-
-### 如何修改
-
-如果您决定修改，可以使用以下命令：
-
-**方式 1：直接修改（固定为 require）**
-```go
-// 文件：internal/db/highgo_impl.go 第 43 行
-q.Set("sslmode", "require")
-```
-
-**方式 2：可配置（推荐）**
-
-如果希望让用户可以选择 sslmode，可以修改为：
-
-```go
-// 在 getDSN 方法中
-sslmode := "disable" // 默认值
-if config.SSLMode != "" {
-    sslmode = config.SSLMode
-}
-q.Set("sslmode", sslmode)
-```
-
-然后在 `internal/connection/connection.go` 的 `ConnectionConfig` 结构体中添加字段：
-
-```go
-type ConnectionConfig struct {
-    // ... 现有字段
-    SSLMode string `json:"sslMode,omitempty"` // SSL 模式：disable, require, verify-ca, verify-full
-}
-```
-
-前端 UI 也需要相应添加 sslmode 选择控件。
-
-### 测试建议
-
-修改后请务必测试：
-
-1. **SSL 启用测试**：
-   - 连接配置了 SSL 的 HighGo 服务器
-   - 验证连接成功
-
-2. **SSL 禁用测试**：
-   - 连接未配置 SSL 的 HighGo 服务器
-   - 验证是否会报错（如果设置为 `require` 会报错）
-
-3. **兼容性测试**：
-   - 测试现有的 HighGo 连接配置是否仍然可用
-
-## 二、其他可选优化
-
-### 1. 默认端口提示优化
-
-**文件**：`frontend/src/components/ConnectionModal.tsx`
-
-**当前状态**：HighGo 的默认端口已正确设置为 5866
-
-**建议**：无需修改，已符合官方规范
-
-### 2. 默认数据库名称
-
-**文件**：`internal/db/highgo_impl.go:33`
-
-**当前代码**：
-```go
-if dbname == "" {
-    dbname = "highgo" // HighGo default database
-}
-```
-
-**建议**：无需修改，已符合官方规范（默认数据库为 `highgo`）
-
-### 3. 默认用户名
-
-**当前状态**：未在代码中硬编码默认用户名
-
-**瀚高官方默认**：`sysdba`
-
-**建议**：
-- 可以在前端 UI 的 HighGo 连接表单中，将用户名输入框的 placeholder 设置为 `sysdba`
-- 但不建议硬编码默认值，让用户自行输入更安全
-
-## 三、总结
-
-### 必须修改的项目
-- ✅ **无**（当前代码已基本符合规范）
-
-### 建议修改的项目
-1. **sslmode 配置**（根据实际环境决定）
-   - 开发环境：保持 `disable`
-   - 生产环境：修改为 `require`
-
-### 可选优化的项目
-1. 将 sslmode 改为可配置（需要修改前后端）
-2. 前端 UI 添加 sslmode 选择控件
-3. 用户名输入框添加 `sysdba` 提示
-
-## 四、修改优先级
-
-**优先级 1（高）**：
-- 集成瀚高 SM3 驱动（参考 `HighGo_SM3_Integration_Guide.md`）
-
-**优先级 2（中）**：
-- 根据部署环境调整 sslmode 配置
-
-**优先级 3（低）**：
-- 将 sslmode 改为可配置
-- UI 优化（placeholder 提示等）
-
-## 五、下一步行动
-
-建议按以下顺序执行：
-
-1. **先集成 SM3 驱动**（参考集成指南）
-2. **测试基本连接功能**（使用 sslmode=disable）
-3. **如果生产环境需要 SSL**，再修改 sslmode 配置
-4. **验证所有功能正常**后，考虑可选优化项
-
----
-
-**注意**：所有代码修改都应该在集成 SM3 驱动并验证基本功能正常后再进行。

-# HighGo SM3 国密驱动集成指南
-
-## 一、背景说明
-
-HighGo（瀚高）数据库需要使用支持 SM3 国密认证的 PostgreSQL 驱动。瀚高官方提供了基于 `lib/pq` 的安全增强版本。
-
-## 二、集成步骤
-
-### 步骤 1：下载瀚高 pq 驱动
-
-1. 访问百度网盘链接：
-   ```
-   https://pan.baidu.com/s/1xuz6uJz0utRgKWecXhpOiA?pwd=o0tj
-   ```
-
-2. 下载驱动源码压缩包
-
-### 步骤 2：放置驱动源码
-
-1. 在项目根目录创建 vendor 目录（如果不存在）：
-   ```bash
-   mkdir -p vendor/highgo-pq
-   ```
-
-2. 解压下载的驱动源码到 `vendor/highgo-pq/` 目录
-
-3. 确保目录结构如下：
-   ```
-   GoNavi/
-   ├── vendor/
-   │   └── highgo-pq/
-   │       ├── go.mod
-   │       ├── conn.go
-   │       ├── ... (其他 pq 驱动源文件)
-   ```
-
-### 步骤 3：修改 go.mod
-
-在 `go.mod` 文件末尾添加 replace 指令：
-
-```go
-replace github.com/lib/pq => ./vendor/highgo-pq
-```
-
-完整示例：
-```go
-module GoNavi-Wails
-
-go 1.24.3
-
-require (
-    // ... 现有依赖
-    github.com/lib/pq v1.11.1
-    // ... 其他依赖
-)
-
-// 在文件末尾添加
-replace github.com/lib/pq => ./vendor/highgo-pq
-```
-
-### 步骤 4：更新 HighGo 连接配置（可选）
-
-根据瀚高官方文档，建议修改 `internal/db/highgo_impl.go:43` 的 sslmode：
-
-**当前代码**：
-```go
-q.Set("sslmode", "disable")
-```
-
-**建议修改为**（瀚高默认）：
-```go
-q.Set("sslmode", "require")
-```
-
-> ⚠️ 注意：如果您的 HighGo 服务器未配置 SSL，保持 `disable` 即可。
-
-### 步骤 5：验证集成
-
-1. 清理依赖缓存：
-   ```bash
-   go clean -modcache
-   ```
-
-2. 重新下载依赖：
-   ```bash
-   go mod download
-   ```
-
-3. 编译项目：
-   ```bash
-   go build ./...
-   ```
-
-4. 测试 HighGo 连接：
-   - 启动应用
-   - 创建 HighGo 连接
-   - 测试连接是否成功
-
-## 三、重要说明
-
-### ⚠️ 影响范围
-
-使用 `go.mod replace` 会**全局替换** `github.com/lib/pq` 驱动，这意味着：
-
-1. **PostgreSQL 连接也会使用瀚高驱动**
-2. **需要验证瀚高驱动对标准 PostgreSQL 的兼容性**
-
-### 兼容性验证
-
-集成后，请务必测试：
-
-1. ✅ HighGo 数据库连接（SM3 认证）
-2. ✅ 标准 PostgreSQL 连接（确保仍然可用）
-
-如果标准 PostgreSQL 连接失败，说明瀚高驱动不完全兼容，需要考虑其他方案。
-
-### 回滚方案
-
-如果集成后出现问题，可以快速回滚：
-
-1. 删除 `go.mod` 中的 replace 指令
-2. 删除 `vendor/highgo-pq/` 目录
-3. 运行 `go mod tidy`
-4. 重新编译
-
-## 四、瀚高驱动特性
-
-根据官方文档：
-
-- **包路径**：`github.com/lib/pq`（与标准版相同）
-- **驱动名**：`postgres`（与标准版相同）
-- **SM3 支持**：自动启用国密认证
-- **默认端口**：5866
-- **默认数据库**：`highgo`
-- **默认用户**：`sysdba`
-- **sslmode 默认**：`require`
-
-## 五、故障排查
-
-### 问题 1：编译失败
-
-**现象**：`go build` 报错找不到 `github.com/lib/pq`
-
-**解决**：
-1. 检查 `vendor/highgo-pq/` 目录是否存在
-2. 检查 `go.mod` 中 replace 路径是否正确
-3. 运行 `go mod download`
-
-### 问题 2：HighGo 连接失败
-
-**现象**：连接 HighGo 时报认证错误
-
-**解决**：
-1. 确认瀚高驱动已正确替换（检查 `go.mod`）
-2. 确认 HighGo 服务器支持 SM3 认证
-3. 检查用户名、密码、端口是否正确
-
-### 问题 3：PostgreSQL 连接失败
-
-**现象**：集成后标准 PostgreSQL 无法连接
-
-**解决**：
-1. 这说明瀚高驱动不完全兼容标准 PostgreSQL
-2. 需要考虑条件编译或其他隔离方案
-3. 临时回滚：删除 replace 指令
-
-## 六、后续优化建议
-
-如果发现瀚高驱动与标准 PostgreSQL 不兼容，可以考虑：
-
-1. **条件编译**：使用 Go build tags 分别编译两个版本
-2. **动态驱动注册**：如果瀚高驱动支持自定义驱动名
-3. **联系瀚高技术支持**：咨询官方兼容性方案
-

+# pq - A pure Go postgres driver for Go's database/sql package
+
+[![GoDoc](https://godoc.org/github.com/lib/pq?status.svg)](https://pkg.go.dev/github.com/lib/pq?tab=doc)
+
+## Install
+
+	go get github.com/lib/pq
+
+## Features
+
+* SSL
+* Handles bad connections for `database/sql`
+* Scan `time.Time` correctly (i.e. `timestamp[tz]`, `time[tz]`, `date`)
+* Scan binary blobs correctly (i.e. `bytea`)
+* Package for `hstore` support
+* COPY FROM support
+* pq.ParseURL for converting urls to connection strings for sql.Open.
+* Many libpq compatible environment variables
+* Unix socket support
+* Notifications: `LISTEN`/`NOTIFY`
+* pgpass support
+* GSS (Kerberos) auth
+
+## Tests
+
+`go test` is used for testing.  See [TESTS.md](TESTS.md) for more details.
+
+## Status
+
+This package is currently in maintenance mode, which means:
+1.   It generally does not accept new features.
+2.   It does accept bug fixes and version compatability changes provided by the community.
+3.   Maintainers usually do not resolve reported issues.
+4.   Community members are encouraged to help each other with reported issues.
+
+For users that require new features or reliable resolution of reported bugs, we recommend using [pgx](https://github.com/jackc/pgx) which is under active development.

+# Tests
+
+## Running Tests
+
+`go test` is used for testing. A running PostgreSQL
+server is required, with the ability to log in. The
+database to connect to test with is "pqgotest," on
+"localhost" but these can be overridden using [environment
+variables](https://www.postgresql.org/docs/9.3/static/libpq-envars.html).
+
+Example:
+
+	PGHOST=/run/postgresql go test
+
+## Benchmarks
+
+A benchmark suite can be run as part of the tests:
+
+	go test -bench .
+
+## Example setup (Docker)
+
+Run a postgres container:
+
+```
+docker run --expose 5432:5432 postgres
+```
+
+Run tests:
+
+```
+PGHOST=localhost PGPORT=5432 PGUSER=postgres PGSSLMODE=disable PGDATABASE=postgres go test
+```
