A related question: does anyone has a function to call syslog()? I
would like to set up triggers which logs with the syslog system, but
only some events (so debug_print_query is not for me).

I cannot write this function in Python (because it exists only as a
safe language), I can do it in Perl but Perl in PostgreSQL does not
have global variables so I have to openlog() each time (I'm afraid,
although I didn't benchmark, that it may slow down the
system.). Before I study C or Tcl, does anyone has a working solution?
