Npgsql with PostgreSQL: Can't see uncommitted changes with UNCOMMITTED READ

I'm using Npsql with PostgreSQL. I want to see uncommitted changes of one transaction in a different one. This is how I create my connection and transaction: ``` // create connection m_Connection = new NpgsqlConnection(connectionString); m_Connection.Open(); //create transaction m_Transaction = m_Connection.BeginTransaction(IsolationLevel.ReadUncommitted); ``` In one thread I insert a row like so: ``` NpgsqlCommand command = CreateCommand("INSERT INTO TABLEA ....", parameters, commandTimeout) command.ExecuteNonQuery(); ``` and process something else without committing or rolling back the transaction. In a different thread I read a row like so: ``` NpgsqlCommand command = CreateCommand("SELECT COUNT(*) FROM TABLEA", parameters, commandTimeout); command.ExecuteScalar(); ``` but somehow I don't see the results of the first INSERT. I don't see the results of the insert in pgAdmin either (even after running SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED). What am I doing wrong? Any help will be appreciated.
