Overwhelming DEBUG messages

I know this should probably go to pgsql-general or more likely pgsql-novice,
but I'm not willing to subscribe either (tee-hee). Also, I have searched the
archives and the docs (packed with the source, if there is anything else)
but didn't find the answer.

My problem is: I'd like to see DEBUG messages in the server log, but if I
set SERVER_MIN_MESSAGES to debug (also tried debug1 and debug5), the log
gets filled with these:

2003-05-08 18:39:57 [12788] DEBUG: StartTransactionCommand
2003-05-08 18:39:57 [12788] DEBUG: CommitTransactionCommand

Is there a way to configure postgres (including compile-time) not to log
such in the server log?
