filter statements in logs

Hi,

A client has a web system that uses ADODB for php, and that driver is
executing "select version()", "SET DATESTYLE TO 'ISO'" and at least
one or two more statements a *lot* of times (almost 1000000 times in 3
hours, and this is just "select version()"), i tried to understand why
but it seems it is for knowing the correct way of looking in catalogs.

But this is just noise in the logs. And when i try to use pgFouine to
analyze logs it shouts because of the size of them, almost 450Mb in a
few hours.

My question: is there a way to avoid logging some predefined statements?
