What feature do you specifically need as an alert? Just writing
the warning into the logfile is enough? Or need to notify by
using SNMP trap message? Though I'm not sure if this is a role
of Postgres. </pre></blockquote><br /> It's impossible for the database to have any idea whatsoever how people are
goingto want to be alerted. Provide functions to monitor things like replication lag, like the number of segments
queuedup to feed to archive_command, and let people build their own alerting mechanism for now. They're going to do
thatanyway, so why waste precious time here building someone that's unlikely to fit any but a very narrow use case?<br
