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

[mmahdium]

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 <TrimmerRootAssembly Include="Npgsql" /> causes the publish to hang indefinitely at the IlcCompile step, consuming excessive memory.

<Project Sdk="Microsoft.NET.Sdk.Web">
  <PropertyGroup>
    <TargetFramework>net9.0</TargetFramework>
    <PublishAot>true</PublishAot>
    <InvariantGlobalization>true</InvariantGlobalization>
  </PropertyGroup>
  <ItemGroup>
    <PackageReference Include="FreeSql.Repository" Version="3.5.204" />
    <PackageReference Include="FreeSql.Provider.QuestDb" Version="3.5.204" />
    <!-- Npgsql is rooted to avoid trimming, but the old version causes hangs -->
    <TrimmerRootAssembly Include="Npgsql" />
  </ItemGroup>
</Project>

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.
