Yes, I do have the message about the failure to start the statistics
collector.
The firewall rules I have are :
# Postgres Statistics Collector
iptables -A INPUT -p udp \
-i lo --sport 32779 --dport 32779 \
-j ACCEPT
iptables -A OUTPUT -p udp \
-o lo --sport 32779 --dport 32779 \
-j ACCEPT
###
iptables -A INPUT -p tcp \
--sport 1024:65535 \
--dport 5432 \
-m state --state NEW,ESTABLISHED,RELATED \
-j ACCEPT
iptables -A OUTPUT -p tcp \
--dport 1024:65535 \
--sport 5432 \
-m state --state ESTABLISHED,RELATED \
-j ACCEPT
but these should be the same both during boot and after the boot process has
finished
