Hi all,

I need to start a postgres daemon and redirrect it's STDERR and STDOUT to a logfile rotator (can't mix them). Here's a sketch of what I'm thinking: 

use IPC::Open3;

our $rotatelogs_bin = '';
our $rotate_size = '10M';    # must end with M, see rotatelogs docs
our $logdir = '/home/ahammond/logtest/log';
our $pg_bin = '/home/ahammond/logtest/belcher.pl';
our $pg_args = '';

# start by opening stdout and stderr loggers

open (STDOUTLOG, "| $rotatelogs_bin $logdir/stdout.log $rotate_size")
or die "Can't open stdoutlog: $!\n";

open (STDERRLOG, "| $rotatelogs_bin $logdir/stderr.log $rotate_size")
or die "Can't open stderrlog: $!\n";

# filehandle manipulation here?

our $pid = open3 (\*STDIN, \*STDOUTLOG, \*STDERRLOG,
                  $pg_bin, $pg_args);

What I'm wondering is about efficiency. Is there a better way to do this? I'd very much like to exec the final call to the postmaster daemon so that I don't have the overhead of a perl instance. Is is possible to detach these processes? Should I be writing this in shell?
