logging modifying statements only

Hello there colleagues,

this question possibly had been asked in past, by I didn't find any definitive
answer.

Is there currently (7.3.2) a way to log only modifying statements (and, surely,
accompanying begin/commit/rollbacks) and skip select's?

Or, should I hack backend/tcop/postgres.c myself? ;-) [yes, I suppose I cound
apparently miss something]

Any ideas?

Sincerely,
D.Marck [DM5020, MCK-RIPE, DM3-RIPN]
