Yes, dblink is a poor precedent to cite because self-connections are a sane behavior in its case. > The problem is that walreceiver might wrongly connect > to *its* server and get stuck because no WAL records arrive for ever. > Since currently we don't allow the standby to accept the replication > connection, the problem will not happen in 9.0, and ISTM we don't need > to address it right now. So I agree to drop. Agreed, this can be put off until we support relay replication. I think it will be an issue then, however. regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers(a)postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers

I've added the ones that should be addressed in the future to the TODO list.

I don't see it mentioned in the TODO, but maybe it's just deemed too elusive to be assigned a todo entry. Was the issue eventually found/solved? thanks, Erik Rijkers -- Sent via pgsql-hackers mailing list (pgsql-hackers(a)postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers

I'd like to see what you do before it gets committed.
