libpq debug

Does anyone know how to set the debug TTY in libpq client library ?
I did not find any example what to put in property pgtty:
 
PGconn *PQsetdbLogin(const char *pghost,
                     const char *pgport,
                     const char *pgoptions,
                     const char *pgtty,
                     const char *dbName,
                     const char *login,
                     const char *pwd)
 
I tried with :
    /dev/ptsxx
    /dev/pts/xx
    ptsxx
    pts/xx
but no result.
 
I've also tried with -o pgoption to set debug log file, but no output was written to that file.
I'm trying to debug some functions and without those two methods, it is very hard work !!!

You can't anymore (it was deemed a security risk some time ago).
The backend ignores the tty argument now.

Is there any other way to debug plpgsql functions through libpq ?
I know that I can catch notice with error message, but this message often
looks like this:

Error near ''''

If I have function with more than one line, message like this does not help.

Thanks for Your previous answer !

Try 7.2 beta ... it reports the line number for plpgsql syntax errors.
