If pqact(1) is logging directly to a file (rather than using the
syslog(8) daemon), then the child processes of pqact(1) will have their
standard error streams directed to "/dev/null" -- at least in version
6.3.0. Therefore, lsof(1) shouldn't show the standard error stream of
any decoder being directed to PIPE files.
