I don't think you can do it in PostgreSQL itself.

I suggest this method:

  Configure PostgreSQL to log to standard output.

  When starting the postmaster, redirect standard output to a named
pipe.

  Before you start PostgreSQL, start up a perl script to read the named
pipe and write to appropriate logs.
