PostgreSql own debug messages

Is it possible to display debug informations in some maybe separate window? I would like to see messages from my procedures. I mean:

RAISE NOTICE 'Some message %', some_variable

RAISE DEBUG 'Some message %', some_variable

and so on.

This is not possible with HeidiSQL currently.

Is that "RAISE NOTICE" PostgreSQL syntax? I can execute that as a query without getting a syntax error.

Yes, It's PostgreSql PL/pgSQL synax. Displayed message level is controled by session variable client_min_messages.

Sorry, a made a typo. I meant I can not execute it without an error:

Syntaxfehler bei »RAISE«
LINE 1: RAISE DEBUG 'Some message %', some_variable
        ^

Understood. You can't run it alone. It is used in function/procedure body. You can try nonymous block f.e.

DO language plpgsql $$
BEGIN
  RAISE NOTICE 'hello, world!';
END
$$;

It looks like on the attached image.

Ok, think I get an idea about messages in Postgres now. HeidiSQL handles MariaDB/MySQL messages, but not for Postgres currently. These seem to work differently, and there might be a bigger modification required to handle these properly.

It would be great for function debugging.
