Native AOT publish hangs at IlcCompile when FreeSql.Provider.QuestDb brings in old Npgsql (5.0.18)

#### 问题描述及重现代码：

Using FreeSql.Provider.QuestDb in a .NET 9.0 ASP.NET Core project with Native AOT publish and `` causes the publish to hang indefinitely at the `IlcCompile` step, consuming excessive memory.

```xml

net9.0
true
true

```

1. `dotnet add package FreeSql.Repository --version 3.5.204`
2. `dotnet add package FreeSql.Provider.QuestDb --version 3.5.204`
3. Enable Native AOT and root Npgsql in the `.csproj` as shown above.
4. Run `dotnet publish -c Release -v diag` and observe hang at `IlcCompile`.
