An error issue when using both ToJson() and UpdateMany() methods or manually enabled multiple UnitOfWorks about abp

[choby]

Applications often make errors after a recent upgrade to.NET 8, I found that if I used tojson() to map jsonb fields, I encountered this problem when I manually enabled multiple UnitOfWorks, and I didn't encounter this problem when I fell back on the tojson() method to HasColumnType("jsonb"). Also note that I made an http request in the UnitOfWork:

Npgsql.NpgsqlException: Exception while writing to stream
---> System.IO.IOException: Unable to write data to the transport connection: Operation canceled.
---> System.Net.Sockets.SocketException: Operation canceled
at Npgsql.Internal.NpgsqlWriteBuffer.d__32.MoveNext() at offset 282
--- End of inner exception stack trace ---

at Microsoft.EntityFrameworkCore.Storage.RelationalCommand.d__14.MoveNext() at offset 779
at Microsoft.EntityFrameworkCore.RelationalDatabaseFacadeExtensions.d__17.MoveNext() at offset 279

When this error occurs, the database fails to log the error log most of the time, Occasionally, however, the following errors are recorded:
ERROR: SAVEPOINT can only be used in transaction blocks

And this problem seems to exist only in certain scenarios, for example, I run it perfectly in debug mode on my macbook, but I run it 3-4 times out of 10 on ubuntu

pgsql: 14
system: ubuntu 22.04
.net: 8.0
efcore 8.0
efcore.pg:8.0.2
abp:8.0.5

hi

This doesn't seem to be related to abp.

If you can reproduce this problem with some code or a simple project, Please share them,

Thanks.
