This time I was using a master/slave pair with the test database in a non-default partition, so neither of those aspects seem to be key after all. I suspect the reason for it being so hard to reproduce is that there's a timing window involved. But that doesn't offer much to go on in terms of being able to make a more reproducible case. regards, tom lane -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
