One solution: write a little function to write out there parameter via
RAISE NOTICE and call this function on the desired places.

I mean something tike this:

test=# create function write_out(text) returns void as $$ begin raise notice '%',$1; end; $$ language plpgsql immutable strict;
test=# select write_out('hint');
NOTICE:  hint

(1 row)

and set 'log_min_messages = notice', then can you find your messages in
the log-file.

Really, I'm not out to destroy Microsoft. That will just be a completely
unintentional side effect.                              (Linus Torvalds)
