Does it work if you direct the output into a file, instead of letting it
come to your terminal (which seems a bit useless anyway)?

I've been bugging dwalsh about the fact that the selinux policy
disallows writes to /dev/tty to things it thinks are daemons;
that seems pretty stupid. But pg_dump isn't a daemon so there's
no reason for it to be restricted this way anyway...

Someone told me there's a rate limit on selinux complaints going to
syslog, to keep it from swamping your logs. I suspect there are some
actual bugs there too, because I've noticed cases where an action was
blocked and there wasn't any log message, nor enough activity to
justify a rate limit. Feel free to file a bugzilla report if you can
get a reproducible case.
