SysLogger subprocess
Here's the core of the logger subprocess.
- no rotation code so far, all syslogFile handling is for testing only
- send_message_to_serverlog needs some careful handling of stderr, in
case pipe writing fails or if after a log process restart redirecting
stderr fails. In these cases, the original stderr should be used.
While looking at pgstat.c to see how to peek for pipe data, I found
readpipe=pgStatPipe[0];
select(readPipe+1, ..);
which is probably usually the same as select(pgStatPipe[1], ..) This fd
arithmetics seem a bit dubious to me.
Regards,
Andreas

No, it's not pgStatPipe[1], it's select(2)'s first argument; max fd in
the sets plus one. Probably your code works because
pgStatPipe[1] == pgStatPipe[0] + 1.
