fully support postgres messages

[eug3nix]

Currently only NOTICE is display in the messages tab.
Add support for other message types: https://www.postgresql.org/docs/current/plpgsql-errors-and-messages.html

It seems that the only case which is not working is "raise exception"
Tested with this:

CREATE OR REPLACE PROCEDURE public.raise_notice(IN s text)
LANGUAGE plpgsql
AS $ procedure $
begin
raise warning '%', s;
raise notice '%', s;
raise info '%', s;
raise log '%', s; --
raise debug '%', s;
--raise exception '%', s;
end;
$ procedure $;

set client_min_messages to 'debug';
call raise_notice('note');
