After an upgrade from 8.0.8 to 8.1.8, I am getting a number of our
scripts failing with 'connection refused' at around 4:00am, which seems
to be when the nightly database backup occurs.
I am using "/usr/bin/pg_dump -Fc -b -c -C" to do the deed.
Has there been a change in behavior, i.e. is the whole databases being
exclusively locked or something that would prevent a connection.
