Ugly output when running tests

Hi folks, I've a weird problem, evertytime I run the tests the output
is filled with sql related stuff.

I've rails 2.3.2 and I get the same result for "rake spec" or "rake
test", please give me some hint.

Thanks!

I've found the culprit!. The method add_index was redefined in an
initializer and it was writing to the standard output instead of
logger.

Very thanks!
