My proposal was to have something separate from message severity
("criticality"). So the problems would continue to be reported as
FATAL, ERROR or WARNING, but if they are just the result of something
the user did wrong, then they get marked as "non critical", but if
there, say, a failure to flush xlog (which currently results in an
ERROR), we could flag it as critical. Grepping the log for critical
messages, regardless of severity, would result in actual action items
for the DBA, without having to grep things out by regex.
Otherwise you have to come up with a lot of messages each keeping the
current behavior of abort the current transaction or not, or terminate
the process or not.
There was also the idea that this would be driven off SQLSTATE but this
seems pretty unwieldy to me.
