        PSQL, PgAdmin4, OmniDB and ADO.NET <http://ADO.NET> but again my
        messages never appear in the log file.

        On very rare occasions, I see my messages the log file if I
        restart the PostgreSql server however restarting the server
        generally does not flush my messages to the log files.

    Do they show up in a client? For example psql:

    [snip]
    test_(aklaver)> select testwithbasictypearguments(1, 2.5, 'test');
    LOG:  Test.TestWithArguments: i = 1, n = 2.5, t = test

I've used the logs successfully here. What are the values of log_min_messages and log_min_error_statement in your postgresql.conf?

The settings are shown in the original post.
