Re: Returned mail: User unknown

Actually I have several cron tasks and they bored me emailing
every night output from psql.
I need emails only if some problems occur.
Ok. I could easily redirect all messages to some file if I would
sure psql returns return code in right way. Then I could
echo this file if RC != 0
grep -v will not works because elog messages are printed to STDERR
so I need something like:
psql -q test < tt.sql 2>&1 | grep -v '^NOTICE:'
but then I will lose return code from psql :-)
Having several flags for different kind of messages would be
very useful.

OK:

trap "rm -f /tmp/$$" 0 1 2 3 15
psql -q test < tt.sql >/tmp/$$ 2>&1
if [ "$?" -ne 0 ]
then echo "Failure"
fi
cat /tmp/$$ | grep -v '^NOTICE:'

Having different psql flags for different elog levels is a bit much.
psql already has too many flags.
