Yes, I have the same issue. I don't think you can do something to stop 
this behaviour. postmaster process creates the directory if not present, 
then tries to create a file in it, and finally launches the syslogger 
subprocess. The file it creates is your .log file. I'm not sure why it 
creates a .log file. Perhaps the postmaster process has no idea at this 
time that the DBA wants csvlog files.

Anyways, you'll only have one .log file because rotation function takes 
care of the log_destination.

This is kind of strange. It should be syslog or csvlog. It shouldn't be 
both of them. Or am I wrong ?
