BTW could you compile psqlODBC from source code? It is possible to disable mylog output in function CC_mapping (it's per record mylog for problems with encoding). I think you don't have such a problem so there is no problem to comment out mylog(...) calls from CC_mapping. This results in much smaller mylog output. Regards, Luf
